00:00:00Jai Hind friends! Welcome to your own family. How are you all?
00:00:29Good evening to everyone. How are you? Are you good? Are you having fun?
00:00:36How are you?
00:00:41Very good.
00:00:43Everyone is live. Very good.
00:00:46Good evening.
00:00:49So, in the last class, we had covered question no. 59.
00:00:55In this class, we will move ahead with question no. 60 and answer all the questions.
00:01:00Okay?
00:01:06Good evening. Good evening.
00:01:09Everyone come live quickly.
00:01:12Quickly.
00:01:14Jai Hind Sir.
00:01:16Jai Hind to everyone.
00:01:18I am also good. How are you all?
00:01:23Tell me.
00:01:26Very good. Very good.
00:01:29Everyone is live.
00:01:31So, are you all excited for the next questions?
00:01:34Finish the discount today.
00:01:37Very good. Very good.
00:01:40We will do as much as we can. There is no need to finish it forcibly.
00:01:49Tell me if you are enjoying the discount.
00:01:54Tell me.
00:01:58Thank you. Thank you.
00:02:11So, let's start the session.
00:02:14Let's start the session.
00:02:16Let's start.
00:02:18Let's go.
00:02:20Very good. Very good.
00:02:22So, we have covered question no. 59.
00:02:25And we have to move ahead with question no. 60.
00:02:28And we have to look at the questions.
00:02:30Let's read question no. 60. Read what was said in question no. 60.
00:02:46Let's go.
00:02:56Let's go. Read the question quickly.
00:02:59See what was said here. Read it quickly.
00:03:11So, let's start here and see what was said in question no. 60.
00:03:16It was said that if the price of the item is increased by 70%
00:03:20and then allow a scheme discount of 5% and 20% on this market price,
00:03:27if the price is paid in cash and additional discount of 20% is allowed,
00:03:31then what is this gain percent?
00:03:33It is a very lovely question.
00:03:35It was said that the value of an item is increased by 70%
00:03:39and then 5% to 20% discount is given on the estimated value.
00:03:43If the value of an item is paid in cash and additional discount of 20% is given,
00:03:48then what is this gain percent?
00:03:51Now, we will tell you this question in two ways.
00:03:54You can do it in two ways.
00:03:56See, you can make your thoughts in that way.
00:04:01So, what will be the first way to make here?
00:04:06Try to understand that way.
00:04:08So, if we talk now,
00:04:10then the first way will be that
00:04:13if we understand that what was the value of our item,
00:04:17let's say we bought it for 100 rupees.
00:04:19After that, the market price will be increased.
00:04:24The value of this item is increased by 70%.
00:04:27Price is increased by 70%.
00:04:29So, if we increase it by 70%, then how much will it be?
00:04:32It will be 170.
00:04:34How much will it be?
00:04:35Now, we give three times discount on the item of 170 rupees.
00:04:40The first discount is of 5 rupees,
00:04:42the second is of 20 rupees,
00:04:44and the third is of 20 rupees.
00:04:46Have you understood this?
00:04:48So, we are giving three discounts on it.
00:04:51So, we will calculate the selling price here.
00:04:53How much will be the selling price?
00:04:55So, we will say that we bought it in this much,
00:04:58and increased it by 70%.
00:05:00Now, if we want to calculate the selling price,
00:05:02then what will we say here?
00:05:03We will say that this is our market price,
00:05:05which is 100% in itself.
00:05:07If we give a discount on it,
00:05:09and that too of 5 rupees,
00:05:11then 5 will be sold in 100,
00:05:13and in how much? In 95.
00:05:15After that, we will again say that this is 100 in itself,
00:05:18and after giving a discount of 20,
00:05:20in how much will it be sold? In 80.
00:05:22Then once again, we will say that there is another discount,
00:05:24then what will happen here?
00:05:26In the item of 100 rupees,
00:05:28the discount of 20 will be sold in 80.
00:05:30What we are doing here is that
00:05:31this was our cost price.
00:05:33Based on this, we made a market,
00:05:35and we want to calculate the selling price here.
00:05:37If our selling price is calculated,
00:05:39then we can easily calculate the profit percent,
00:05:41which my brother will tell here.
00:05:43So, if we talk, then see here.
00:05:45You will say, Guruji,
00:05:47both 0s from 1010 are over,
00:05:49and from this 0,
00:05:51this is also over here.
00:05:53If you subtract from 5,
00:05:55then this will go to your 19 times,
00:05:57and if you subtract from 5, then in 2 times.
00:05:59If you subtract from 2,
00:06:01then this will go to your 18.
00:06:03So, if we see here,
00:06:05then multiply this,
00:06:0717 into 4 becomes 68 here,
00:06:09and after that,
00:06:11how much will be 19 into 8?
00:06:13It will be 152.
00:06:15And how much will it be divided by?
00:06:17If it is divided by 100 below,
00:06:19then my brother will be 100.
00:06:21Now multiply these and divide by 100.
00:06:23So, if you multiply 68 with 152
00:06:25and divide by 100,
00:06:27then how much will you get?
00:06:29So, you are 152 and here is 68.
00:06:31So, what we have learned,
00:06:338 into 2 is 16,
00:06:356 is 1,
00:06:3740 and 12,
00:06:3952 and 1 is 53,
00:06:413 is 5,
00:06:438 is 30,
00:06:4538, 38 and 5 is 43,
00:06:473 is 5,
00:06:494 is 4,
00:06:516 is 6,
00:06:53and 4 is 10,
00:06:550 is 1,
00:06:57and this is 10336.
00:06:59So, if we see here,
00:07:01we will say,
00:07:03how much did we buy?
00:07:05100 rupees.
00:07:07How much did we sell?
00:07:09This much.
00:07:11So, can't we calculate the profit?
00:07:13So, you will say, yes,
00:07:15you can definitely calculate.
00:07:17So, what is the percentage of profit?
00:07:19So, the percentage of profit is
00:07:21profit upon CP into 100.
00:07:23This is what happens, my brother.
00:07:25Now, how much is the profit?
00:07:27This much.
00:07:29This is not a percentage,
00:07:31but if a smart kid will say,
00:07:33he can say this straightly,
00:07:35the profit is more than 100,
00:07:37and the loss is less than 100.
00:07:39So, how much is more than 100?
00:07:41So, 3.36.
00:07:43So, if it is 3.36,
00:07:45then the percentage of profit
00:07:47will be 3.36.
00:07:49And, which option will be there?
00:07:51So, D will be the correct answer.
00:07:53What will be D here?
00:07:55It will be the correct answer.
00:07:57So, what did we say here?
00:07:59We have taken it as CP.
00:08:01So, what will happen?
00:08:03If you give different discount
00:08:05on the market price,
00:08:07the selling price will go up.
00:08:09To take out the profit,
00:08:11we have to say something straightforward,
00:08:13that my brother,
00:08:15look at the things worth 100,
00:08:17and see how much you are selling.
00:08:19The more you sell,
00:08:21the profit will increase,
00:08:23and the less you sell,
00:08:25the loss will increase.
00:08:27Now, we will tell you the second
00:08:29method to solve this.
00:08:31So if we see here, how do we solve this question?
00:08:34Now you will say that you were teaching the formula,
00:08:36then how did you come to this method after the formula?
00:08:39I told you in the middle if I wanted to.
00:08:41Now for the people who were teaching the formula, how will this question be solved?
00:08:45So see, what do we write in the formula?
00:08:48So mp upon cp is equal to 100 plus minus profit or loss
00:08:54and divided by what becomes 100 minus discount.
00:08:58This becomes my brother.
00:08:59Now if you see carefully,
00:09:01you can write mp and cp in the formula.
00:09:05But there is only one place for discount.
00:09:08There is only one place for discount here.
00:09:10And if you see, there are different types of discounts here.
00:09:13One gave 5, then 20 and then 10.
00:09:17So my brother, what do we have to do?
00:09:19We will have to subtract the successive of all three
00:09:21and then write the value that comes after that.
00:09:25This means that if you get different types of discounts in the future,
00:09:29then you will write their successive and then solve here.
00:09:33So it is the same thing, write the successive of these two.
00:09:36So what is the successive of 20 and 20?
00:09:38So the successive of 20 and 20 is the same.
00:09:4120 times 20 minus 20 into 20 divided by 100.
00:09:44I don't think you have any problem with this.
00:09:46So my brother will tell you very easily.
00:09:48Subtract 4 from 40.
00:09:50So if you subtract 4 from 40, then my brother will get 36.
00:09:53So here their discount will be 36.
00:09:55Now how will we get the discount of 5 and 36?
00:09:58So Guruji will say that if you want to subtract 5 from 36,
00:10:01then 5 plus 36 and minus 5 into 36 divided by 100.
00:10:06If we see, then this will be 36 and 5 is 41.
00:10:10And 36 minus 100 is 180, 180 means 1.8.
00:10:14So here if you subtract 1.8 from 41,
00:10:17subtract 1.8 from 41,
00:10:19then how much will you get?
00:10:21So if you subtract 1.8 from 41,
00:10:24then we will get 39.2.
00:10:26How much will we get?
00:10:2839.2.
00:10:29That is, in the future, if you get a lot of discount,
00:10:33one kind, two kinds, three kinds, four kinds,
00:10:36then you will take out the total by compiling the discount of all people.
00:10:40My brother, the successive of these two is this.
00:10:42Suppose this won in both the teams.
00:10:44Now my brother, mix this team with this.
00:10:47So here is the discount.
00:10:49And the same thing is written here in the formula.
00:10:51So you will say that the price of the article you have increased is 70%.
00:10:55That is, if you buy a 100 rupee item,
00:10:57then you increase its market price by 70 and make it 170.
00:11:00And I am not saying this, it has been said in the question
00:11:03that the price is increased by 70%.
00:11:05So take it, brother, you increased the price by 70%.
00:11:08After that, it was said in the question,
00:11:10what will be the gain percent?
00:11:11So gain percent means here 100 plus my brother will be profit.
00:11:15Let's talk about discount, so 100 minus.
00:11:18How much discount have we taken out?
00:11:2039.2.
00:11:21So this will be our 39.2, my brother.
00:11:24It has come.
00:11:25It's a simple thing here.
00:11:27Now if you see, you will say, sir, look here.
00:11:29If you divide 17 by 10, it will be our 1.7.
00:11:33And if you don't want to divide, then let it be like this.
00:11:36There is no problem.
00:11:3717 divided by 10, my brother.
00:11:39Now after that, what will happen here?
00:11:41So 100 plus profit will be done.
00:11:43If we subtract it from 100,
00:11:45so if we subtract it from 100,
00:11:47then you will say, sir, it will be 60.8.
00:11:50How much will it be?
00:11:51So 60.8 will be here, my brother.
00:11:54If there is any problem,
00:11:55if there is any problem somewhere,
00:11:56then tell me, my brother.
00:11:57Okay?
00:11:58Now come here, my brother.
00:12:00Solve next.
00:12:01So 17 into 8, how much will it be, my brother?
00:12:04How much is 17 times 8?
00:12:05Tell me quickly.
00:12:06So 136.
00:12:07So 17 into 8, 136 times 6 is 13.
00:12:1013 times 3 is 1.
00:12:12How much is 17 times 6?
00:12:14102.
00:12:15And 102 and 1, my brother, will be 103.
00:12:17Okay?
00:12:18After that, after a number, there is a decimal.
00:12:20Or you can say that, sir, look,
00:12:22this is not 17 divided by 10,
00:12:24this is 1.7.
00:12:25And when we multiply this 1.7 with it,
00:12:28then we will have this much.
00:12:29Whose will this be equal to?
00:12:31So 100 plus profit.
00:12:32And if I subtract 103 points from this,
00:12:35then this, my brother, will be 3.36.
00:12:38And this will be the percentage of my brother's profit here.
00:12:41So you guys are smart.
00:12:42You can understand everything.
00:12:44You know this thing very well
00:12:46that we can go from this formula.
00:12:48But to go from this formula,
00:12:50we need a single discount.
00:12:52What do we need?
00:12:53We need a single discount.
00:12:54And when will that single discount happen?
00:12:56When three different discounts have been given.
00:12:58Four different discounts have been given.
00:13:00So my brother, we will put their successive here.
00:13:02Okay?
00:13:03That brother, who did this total discount come to?
00:13:06So the total discount is equal to 39.2.
00:13:09So whenever it is written here, it is written total.
00:13:12If two discounts have been given,
00:13:13then they will not add both.
00:13:14No.
00:13:15If three have been given,
00:13:16then they will not add all three.
00:13:17Put their successive.
00:13:18Write discount instead of discount.
00:13:20And write CP instead of CP here.
00:13:22Write MP instead of MP.
00:13:24Your profit will come out.
00:13:26So what was method number one here?
00:13:28What you bought was in this much.
00:13:30If you increase it, it becomes a market.
00:13:32If you give different discounts on that market,
00:13:34it becomes selling.
00:13:35If SP comes from CP,
00:13:37then you can get direct profit.
00:13:38This was method number one.
00:13:39Method number two,
00:13:40method number two is for those people
00:13:42who are formula lovers here.
00:13:44If you assume that
00:13:45two discounts are given,
00:13:46three discounts are given.
00:13:47For them, I have a simple suggestion.
00:13:49Whatever kind of discount you get,
00:13:51either do it by putting successive
00:13:53or by putting ratio,
00:13:54but reach the conclusion of a total discount.
00:13:57When the total discount will come,
00:13:58then you will keep it here.
00:14:00Think for yourself.
00:14:01Will you give 5 instead of D?
00:14:02Or will you write 20 instead of D?
00:14:04Who will you write?
00:14:05So you will write the total of all of them,
00:14:07my brother.
00:14:08I have written the total of D here,
00:14:10and instead of CP,
00:14:11instead of CP,
00:14:12instead of MP,
00:14:13when you solve this,
00:14:1417 divided by 10 is 1.7.
00:14:16If you reduce it by 100,
00:14:17it becomes this much.
00:14:18If you multiply it by this much,
00:14:19it becomes this much.
00:14:20If you reduce it by this much,
00:14:21it becomes this much.
00:14:22The work is over.
00:14:23Now we will see this.
00:14:24When we make one more question,
00:14:26then things will be more clear to you.
00:14:31If there is any problem,
00:14:32then tell me.
00:14:33Let's go.
00:14:34Let's see the next question here.
00:14:35Now assume that
00:14:36I am the only one
00:14:37who is asking you
00:14:38simple questions here,
00:14:39my brother.
00:14:40Okay.
00:14:43Now this question
00:14:44is a simple,
00:14:45easy question.
00:14:46You can do this.
00:14:47Okay.
00:14:48This question is easy.
00:14:49You can do this.
00:14:50You guys do this.
00:14:51Not this.
00:14:52I mean,
00:14:53I want
00:14:54another question like this
00:14:55to be asked here.
00:14:56And here I tell you
00:14:57this in the question.
00:14:58Look.
00:14:59Like I have a simple question.
00:15:00Look here.
00:15:01I am telling you
00:15:02that the cost price
00:15:03of any article
00:15:04is 100 rupees.
00:15:05My brother,
00:15:06the market price
00:15:07of that article
00:15:08is how much?
00:15:09So my brother,
00:15:10the market price
00:15:11is 150 rupees.
00:15:12I have given
00:15:13two discounts on it.
00:15:14Discount 1
00:15:15I have given
00:15:1610 percent.
00:15:17And discount 2
00:15:18I have given
00:15:1920 percent.
00:15:20So you tell me
00:15:21here
00:15:22what will be
00:15:23our profit?
00:15:24What will be
00:15:25our profit,
00:15:26my brother,
00:15:27here?
00:15:28How much will it be?
00:15:29We are asking you
00:15:30here.
00:15:31We are asking you
00:15:32here that
00:15:33what will be
00:15:34our profit in
00:15:35future?
00:15:36I tell you
00:15:37that
00:15:38what will
00:15:39be the
00:15:40profit in
00:15:41future?
00:15:42Ok.
00:15:43You have asked
00:15:44us this question.
00:15:45Now I
00:15:46will tell you
00:15:47its solution.
00:15:48Look.
00:15:49This becomes
00:15:50CP.
00:15:51My brother,
00:15:52here comes
00:15:53MP.
00:15:54You have
00:15:55two discounts
00:15:56here.
00:15:57You have given
00:15:58two discounts
00:15:59and your
00:16:00examiner is
00:16:01asking you
00:16:02what
00:16:03you will say, sir, look, how much did you buy, so you bought it for 100 rupees, we have no problem in this, we have no problem in this,
00:16:11there is no voice, there is a voice, don't cheat, don't lie, okay, now assume that this is the market price and after that two discounts have been given on it,
00:16:21so what will we get straight, we will get the selling price, how will we get it, we will say that this is the market price, which is 100% in itself,
00:16:30if we reduce 10 out of 100, then how much will be our selling, 90, similarly, if you assume that 100 is our market, then reduce 20 out of 100,
00:16:39how much will be the selling, it will be 80, now here, friends, you cut, if you cut from 50, it will be cut in 3 times, if you cut from 50, it will be cut in 2 times,
00:16:47understood, this 0 and this 0 will fly both together, if you cut from 2, it will go in 4 times, 4 into 3, 12, 12 into 9, how much will we get, it will be 108,
00:16:57now what will you say here, how much is the goods, 100 rupees, how much did you sell, 108, understood my point, so from here you will say straight,
00:17:05how much is our profit, so you will say here, Guruji, see, how much is the profit, then 8 rupees, above how much, then above 100,
00:17:13and how much will we do into, then we will do 100%, so this will be our answer, 8%, so from whom did we get this, so from method no. 1,
00:17:21that CP was known, we will continuously put all the discounts on the market price and take out SP, the more the profit, the less the loss,
00:17:30now if someone wants to do this from method no. 2, we said, do it from method no. 2, when did I say no, just do one thing first,
00:17:39use all the types of discounts given and take out a successive discount, that is, take out a total discount, my brother, how much will you get in total,
00:17:48so to take out the total, what will you do here, 10, 20, and here minus 10 into 20, my brother, 100 here, so what will you say here,
00:17:58so you will say, sir, subtract 2 from 30, subtract 2 from 30, so my brother, 28 will come, subtract 2 from 30, so how much will come, so 28 will come,
00:18:06now after that here, you see, what will you say in the question, sir, the formula we have read, what have we read in that formula,
00:18:13MP upon CP will be equal to 100 plus profit and divided by 100 minus discount, now sir, keep the value, how much have we bought,
00:18:23so we will say that we have bought 100 and how much is our market, so our market is 150, after that, instead of 100 plus profit,
00:18:32100 plus profit will be there and instead of 100 minus discount, how much is our discount, so our discount will be 28,
00:18:40our discount will be 28, so this will be ours, if you see here, then cut here, sir, cut from 50 in 3 times, cut from 50 in 2 times,
00:18:49now see here, so above this 3 divided by 2 has become my brother, into this part, you will subtract 28 from 100, 72 will come,
00:18:58and this 72 will go in multiplying above, this will be equal to 100 plus my brother profit, if you see, then you will cut from 2 in 36 times,
00:19:0736 into 3, my brother, how much will be 108 and 108 will be equal to 100 plus profit, now tell me one thing, my brother,
00:19:15how much will you add in 100 that 108 will come, the natural thing is 8%, so if you answer here, then what will you say in the answer,
00:19:23subtract 100 from 108, so the value of profit is coming out of 8%, so in this way, my brother, you can understand here,
00:19:33I have an example of examples, my brother, if I want, I can explain to you in any way, okay, but I try not to tell 4-5 methods here,
00:19:42so that you can understand things in a better way, you can learn here, you understand what I am talking about,
00:19:49so what was our first method, that we go from series, and the second one is our formula, you can go from whatever you want to go,
00:19:57now here we will do this question, now hold 61, first you see 62, this is a very easy question, my brother, here you can say very easily,
00:20:06that sir, look at the market price, it is 840, after that look at the discount, it is 15%, after that look at the profit, it is this much,
00:20:14so how much will be our CP, my brother, this came directly on top of the formula, and even a child knows a formula, and what does he know,
00:20:23that brother, look at the CP in MP upon, it is equal to 100 plus minus profit or loss divided by 100 minus discount,
00:20:33this is a simple thing, you tell me how much is the market of the article, it is 840, after that how much is its CP,
00:20:40so we have to find out the CP only, so we will write it here, what will we do in profit, we will add, profit is 19,
00:20:46so 100 multiplied by 19, my brother, it will be 119, and how much is our discount, it is 15, subtract 15 from 100, it will be 85,
00:20:53if we cut here, then we will cut from 17 in 7 times, we will cut from 17 in 5 times, if we cut from 7, then it will go in 120 times,
00:21:015 times of 120, 5 multiplied by 120, my brother, it is 600, and how much will be our CP, it will be 600,
00:21:07so sometimes if such easy questions come in the parlour, you will throw them away, sometimes if it is difficult, then learn to fly them too,
00:21:15Deepak says that 10 and 20 will have a successive 32, you are studying discount, my brother, you are studying successive decrease,
00:21:22not successive increase, if you were studying successive increase, then 10 plus 20 plus 10 multiplied by 20 divided by 100,
00:21:28so it will be 32, if we add in compound interest, then it will be 32, and if we subtract in discount, then it will be 28,
00:21:34this is a basic thing, I have taught you in the first class, and you can learn this in the first class,
00:21:40come on, my brother, you will not know when the battery will run out, no one will see,
00:21:46so here my brother, see question no. 61, question no. 61 is on the same fundamental, and it is asked in Siegel 2021,
00:21:52the cost price in the market price of item is this much and this much, this is CP and this is our MP,
00:21:57when it is sold at a discount of X percent, profit is this much, find the value of X,
00:22:02will you not be able to make this question, my brother, you can make it simple, formula sir,
00:22:06you see, I have given CP, I have given MP, I have given profit, I have given discount,
00:22:10and when these four things have been given, then we apply the formula directly there and get our answer from the formula,
00:22:16and our formula was Zindabad, Zindabad is, and Zindabad will be, so MP upon CP is equal to 100 plus profit,
00:22:26and what will be divided by 100 minus, then my brother will be discounted, if we talk about MP,
00:22:32so how much is our MP, then our MP is 900, how much is our CP, our CP is 720,
00:22:38if we talk about profit, then our profit is 100 times 5X plus 3, my brother,
00:22:44how much is in 5X, how much is in 5X, then 3 is here, and if we talk about discount,
00:22:50then our discount will be 100 minus X, you cut here and understand the thing,
00:22:56if you cut here, in 18 to 5 times, in 18 to 4 times, a smart person will also say,
00:23:02multiply 5 by all this, how much will be 5 into 100, then brother will be 500,
00:23:08how much will be 5 into X, then minus 5X will be, how much will be 4 into this, then 400 will be,
00:23:14and if we multiply 4 with this, 4 into 5 will be 20 divided by 3X, my brother,
00:23:20what will be in 20 divided by 3, it will be X, it is clear, now tell me my brother,
00:23:26minus 400 from 500, then this will be 100, and this part will go there,
00:23:32so 5X plus 20 divided by 3 will be X, if we see here, then we will say,
00:23:393 into 5, 15, 15 plus 20, my brother, 35 divided by 3 will be the value of X,
00:23:45can you cut more, you can cut more, why not, cut from 5 in 7 times,
00:23:51cut from 5 in 20 times, if we multiply by 3, then this will be 60 divided by 7,
00:23:57this is the value of X, if we cut more, then see here, 7 will be 8 times 56,
00:24:03how much is left, 4, 8 right, 4 times 7%, this is my brother's option number C,
00:24:09which is the correct answer, so what you cannot make, let there be any question in CGL,
00:24:14let there be any question in CHSL, let there be any question in MAILS,
00:24:18that question will not be there for you, it will be there, you will throw it away,
00:24:22I always say that always read maths where you understand,
00:24:26I have never said to any child that if you have studied my name, then come to my name,
00:24:30no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no
00:25:00no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no
00:25:30no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no
00:26:00no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no
00:26:30no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no
00:27:00You, my brother, tell me here, how much profit will you get?
00:27:04Tell me.
00:27:05Tell me quickly, how much will it be?
00:27:06Use your brain.
00:27:25Tell me, brother.
00:27:26Come on.
00:27:27So what will you say here?
00:27:28You will say here, sir, see what we have read, my brother, what we have read, so I tell you,
00:27:35what you have read here is that the cp in MP upon is equal to 100 plus or minus profit
00:27:43or loss of my brother and here is 100 minus discount.
00:27:47I have taught you this, but if you look here, one profit on one discount and another profit
00:27:54on another discount.
00:27:55So what will we do here?
00:27:56We will say, sir, see what is MP upon CP, it is fixed, so we will call it P1, L1 or D1
00:28:03here and we will call it my brother.
00:28:05See, there is a D1 discount on P1 profit.
00:28:07In the same way, my brother, if you give them any other profit tomorrow, any other profit
00:28:12or any other loss, then the discount on it will be how much?
00:28:16My brother will be D2.
00:28:18Remember.
00:28:19Because if the ratio of these two is 7 and 5, then it will remain 7 and 5, then it will
00:28:23remain fixed.
00:28:24They can change that a particular profit for a particular discount, a particular profit
00:28:28for a particular discount.
00:28:29So what were you using so far?
00:28:31What were they doing here?
00:28:33You were making questions by using this part.
00:28:36Now my brother, what will you use here?
00:28:38Now my brother, you will use this part that this discount on one P1, then how much will
00:28:43be the discount on the next P2?
00:28:45You will have to make it.
00:28:46So just make it and see my brother here.
00:28:48Because this ratio is fixed.
00:28:50The same ratio will come in this and the same ratio will come in this.
00:28:53So if you see, then sir, see what is the value of P1?
00:28:56So if you see, the value of P1 is 10.
00:28:58So what will you say?
00:28:59Sir, there is a profit of 10 in 100 and how much is the discount?
00:29:02How much is D1?
00:29:03So our D1 is 20.
00:29:04So 100 minus D1 will be equal to my brother.
00:29:07After that, what will we say here?
00:29:09So 100 plus P2.
00:29:10No one knows P2.
00:29:11And my brother, what is D2?
00:29:13D2 is 10.
00:29:14So here we will say 100 minus my brother will be 10.
00:29:17You tell me one thing, sir, how much will this be for us?
00:29:20110 and how much will this be for us?
00:29:2280.
00:29:23If you look here, then this 100 plus will be our P2 and if you look here, then my brother
00:29:27will be 90.
00:29:28If we talk about my brother here in questions, you will say that 0 has blown our 0.
00:29:33It is a very good thing.
00:29:35Multiply it, sir.
00:29:36If you multiply 9, then 990 and how much is in the pot?
00:29:408.
00:29:41And who will this be equal to?
00:29:42So 100 plus my brother P2.
00:29:44If you solve one more line, then my brother will go and get the answer here.
00:29:48Okay.
00:29:49You bring this 100 and minus it.
00:29:51So when you bring 100 and minus it, then from 990 divided by 8, you minus 100 here.
00:29:57This will be your brother P2.
00:29:59If you look here, then 8 into 100 will be 800.
00:30:038 into 100 is 800.
00:30:04If you subtract 800 from 990, then 8 in 190 and this will be equal to our P2.
00:30:10If we look at 8, then 8 times 2 is 16 and 30 has come.
00:30:158 times 3 will be 24 and look at 8 times 2 will be 16 and 30.
00:30:228 times 3 is 24 and 60 is ok.
00:30:258 times 7 is 56, 8 times 5 is 40 and this is our 23.75.
00:30:29This is our correct answer.
00:30:31What will happen to our 23.75?
00:30:33The answer will be absolutely right.
00:30:35So, if you reduce the discount, your profit increases.
00:30:38Remember this.
00:30:40And you have learned this very well through this formula.
00:30:45Very well.
00:30:47So, we repeat the same question here again.
00:30:50When an item is sold at a 5% discount,
00:30:53how much is the profit?
00:30:55Suppose, our discount is 5%.
00:30:59So, what will be our profit?
00:31:01Our profit will be 14%.
00:31:03Now, if the discount is 11%,
00:31:06what will be the profit?
00:31:08If the discount is 11%,
00:31:10what will be the profit?
00:31:12It's very simple.
00:31:14Remember the formula.
00:31:16100 plus P1 divided by 100 minus D1.
00:31:20It will be equal to 100 plus P2
00:31:23divided by 100 minus D2.
00:31:26Understood?
00:31:28Now, add the profit to the previous one.
00:31:30How much is the profit? 14%.
00:31:32How much will be the profit?
00:31:34It's 114.
00:31:36Now, subtract 5 from 100.
00:31:38It's 95.
00:31:40Now, add 100 plus P2.
00:31:42It's D2.
00:31:44Subtract 11 from 100.
00:31:46It's 89.
00:31:48If you have any problem,
00:31:50let me know.
00:31:52If you subtract from 19,
00:31:54it's 6.
00:31:56If you subtract from 19,
00:31:58it's 5.
00:32:00It's 56.
00:32:02It's 58.
00:32:04It's 53.
00:32:06It's 5.
00:32:08It's 100 plus P2.
00:32:10Now,
00:32:12divide 5 by 5.
00:32:14If you want to divide any number by 5,
00:32:16double it.
00:32:18It's 1534.
00:32:20It's 1068.
00:32:22It's 100 plus P2.
00:32:24It's 100 plus P2.
00:32:26It's 100 plus P2.
00:32:28Subtract it from this.
00:32:30Subtract it from 106.8.
00:32:32It's 6.8%.
00:32:34It's equal to
00:32:36P2.
00:32:38It's 6.8%.
00:32:40D is
00:32:42correct.
00:32:46Did you understand?
00:32:48If you have any problem, let me know.
00:32:50Keep the concept clear.
00:32:52You should know what to apply.
00:32:54Practice your sheet multiple times.
00:32:56You will get
00:32:58maximum benefit.
00:33:00You will get maximum benefit.
00:33:04Next question.
00:33:06It's a similar type of question.
00:33:08I have made a sheet.
00:33:10I know the types.
00:33:12When a shopkeeper gives a discount of
00:33:1417.5 on the market price of
00:33:16item, gain is 32.
00:33:18If he gives a discount of D,
00:33:20gain will be 36.
00:33:22What will be the value of D?
00:33:24It's a simple question.
00:33:26The value of D1 is
00:33:2817.5.
00:33:30If D1 is equal to
00:33:32P1, then P1
00:33:34value is 32.
00:33:36P1 value is
00:33:3832.
00:33:40If D2 is
00:33:42equal to
00:33:44P2, then
00:33:46P2 will be
00:33:4836.
00:33:50Is it possible or not?
00:33:52Is it possible or not?
00:33:54Is it possible or not?
00:33:56If it is possible,
00:33:58then this question is for you.
00:34:00This is a homework for you.
00:34:02This is not a hold.
00:34:04This is a homework for you.
00:34:06This is PGW.
00:34:08Do it yourself.
00:34:10Have confidence.
00:34:12When you can answer any question,
00:34:14you will have confidence.
00:34:16You can pass this test.
00:34:18Do you understand?
00:34:20Let's go to the next question.
00:34:22Let's go to the next question.
00:34:24What is the next question?
00:34:26It is said that a shopkeeper
00:34:28makes a profit of this much
00:34:30after allowing a discount of this much.
00:34:32Find this profit percent if it is sold
00:34:34at market price allowing no discount.
00:34:36I will make this question
00:34:38because of this word.
00:34:40What is the word here?
00:34:42Allowing no discount.
00:34:44Let's explain this whole thing.
00:34:46Let's explain this whole thing.
00:34:48You will say,
00:34:50a shopkeeper makes a profit of 12.5%
00:34:52when he allows a discount of 10%.
00:34:54a shopkeeper makes a profit of 12.5%
00:34:56when he allows a discount of 10%.
00:34:58When there is a discount of 10%,
00:35:00what will be the profit?
00:35:02The profit will be 12.5%.
00:35:04The profit will be 12.5%.
00:35:06Now the question says,
00:35:08Find his profit percentage
00:35:10if the article is sold at market price
00:35:12allowing no discount.
00:35:14Let me tell you one thing.
00:35:16If you have sold your article at market price
00:35:18If you have sold your article at market price
00:35:20then it means that
00:35:22you have not given any discount.
00:35:24You have not shown any mercy.
00:35:26You have not shown any love.
00:35:28You have not given any discount.
00:35:30You have become rigid.
00:35:32You have become rigid that
00:35:34you will sell it at market price
00:35:36and will not give any discount.
00:35:38If you give 0% discount
00:35:40then what will be your profit?
00:35:42Common sense says that
00:35:44if you reduce the discount
00:35:46then you will get more profit.
00:35:48How will you solve it?
00:35:50100 plus P1
00:35:52divided by 100 minus D1
00:35:54It's a simple thing.
00:35:56It will be equal to
00:35:58100 plus P2
00:36:00divided by 100 minus D2
00:36:02Did you understand?
00:36:04P1's value is 12.5%
00:36:06If we add 12.5% to 100
00:36:08then it will be 112.5
00:36:10D1's value is 10
00:36:12If we reduce 10 to 100
00:36:14then it will be 90
00:36:16If we do not know P2's value
00:36:18then we will say 100 plus P2
00:36:20If we reduce 0 to 100
00:36:22then it will be 100
00:36:24Nothing will change.
00:36:26If we subtract 0.5 from D1
00:36:28then it will be 0
00:36:30If we subtract 0.5 from D1
00:36:32then it will be 0
00:36:34If we subtract 0.5 from D1
00:36:36then it will be 9
00:36:38If we subtract 9 from D2
00:36:40Now you tell me, if you subtract 100 from 125, how much will it be?
00:36:4525, and this will be the value of P2.
00:36:48So what will be the value of P2? 25%.
00:36:51What will be the value of P2, Munna? 25%.
00:36:55It's a simple thing.
00:36:56By giving one discount and one profit, ask for another discount and another profit.
00:37:00You have to apply the formula here.
00:37:03Is it clear, brother?
00:37:05Sir, your practice sheet and classroom sheet is amazing.
00:37:08Brother, it takes a lot of effort. I put a lot of effort in the content.
00:37:11Remember, application students have to put in a lot of effort.
00:37:15Okay?
00:37:16It takes a lot of effort.
00:37:17Don't think that your practice sheet is the same, we'll put it in.
00:37:20No.
00:37:21It takes a lot of effort on that too.
00:37:23You have to look at the level of questions, you have to look at the quality of solutions.
00:37:26It takes a lot of effort on that too.
00:37:28The more effort it takes in the classroom sheet, the double the effort it takes in the practice sheet.
00:37:32Why? Because I have to write the solution in it.
00:37:34Okay?
00:37:35It's easy to teach, you can explain.
00:37:37But when you write the solution, then there is typing, then there is proofreading.
00:37:40Okay?
00:37:41So it takes a lot of effort.
00:37:43Okay?
00:37:44Just think that you can be made perfect from all four directions.
00:37:47And you can get 50 out of 50 in maths.
00:37:51Come here.
00:37:52A lovely question from CRPF Ed Constable, no. 66.
00:37:54What was said?
00:37:55Read it.
00:37:56A dealer sold a music system for Rs. 18,920 with a discount of 12% and earned a profit of 25%.
00:38:04What would have been the percentage of profit earned if no discount was offered?
00:38:08A very easy question.
00:38:09Now what do people think?
00:38:11Like when they read this question, they think,
00:38:13Oh my God, the first question is from Ed Constable.
00:38:15It will be very tough.
00:38:16Because the air is made of it.
00:38:18Second, such big data has been given.
00:38:20Oh my brother, what did I teach you all my life?
00:38:23When it comes to percent,
00:38:25when it comes to percent,
00:38:27there is no use of data there.
00:38:30No use at all.
00:38:31A sensible person will never do this.
00:38:34He will directly say,
00:38:35Sir, if the discount is 12%, then the profit is 25%.
00:38:39So he will say this,
00:38:40Master Sir had taught.
00:38:41And what did Master Sir teach?
00:38:43If the discount is 12%,
00:38:45then how much profit will we get?
00:38:47Then we will get 25%.
00:38:48Now what is said in the question?
00:38:50What would have been the percentage of profit if no discount was offered?
00:38:53If we don't give him a discount,
00:38:55if we give him zero discount,
00:38:57if we don't give him any discount,
00:38:59if we don't give him any discount,
00:39:00if it is a photocopy of 65,
00:39:02then what will be our profit?
00:39:04Now what difference does it make to us?
00:39:06How much did you buy?
00:39:07How much did you sell?
00:39:09What was your market price?
00:39:10Does it make any difference to us?
00:39:11Does it make any difference to us?
00:39:12We have to subtract 3 out of 4 things.
00:39:15Does it make any difference to us?
00:39:16This is our job.
00:39:18So this is our job.
00:39:19So see, the whole world is playing in two different directions.
00:39:22You take it away.
00:39:24What will you say?
00:39:25100 plus P1
00:39:26divided by my brother 100 minus D1
00:39:28will be equal to 100 plus P2
00:39:31and divided by 100 minus D2.
00:39:33That's it.
00:39:34The work is over.
00:39:35If we look at the value of P1, it is 25.
00:39:37If we add 25 to 100,
00:39:39how much will it be?
00:39:40It will be 125.
00:39:41If we look at the value of D1, it is 12.
00:39:43If we subtract 12 from 100,
00:39:45it will be 88.
00:39:47If no one knows the value of P2,
00:39:49it will be ours.
00:39:51And if we look at the value of D2,
00:39:52if we subtract 0 from 100,
00:39:54it will be 100.
00:39:56Did you understand?
00:39:57Now if we look here,
00:39:58what will we say?
00:39:59We will say, sir, it is a little difficult here.
00:40:01There is no problem.
00:40:03So what if it is difficult?
00:40:04We will do it.
00:40:05Okay?
00:40:06If you look here,
00:40:07you will say, sir, take this 100 and go here.
00:40:09So this is our 1, 2, 5, 0, 0.
00:40:12Divide with whom?
00:40:13With 88.
00:40:14And this will be equal to our 100 plus my brother P2.
00:40:18If you divide here,
00:40:20then first divide by 88 at once.
00:40:22We will have 12 and 25.
00:40:24My brother 377.
00:40:26Now how much will be the multiplication of 88?
00:40:284 times my brother.
00:40:29Okay?
00:40:30So how much will be the multiplication of 88 here?
00:40:32So here it means 4 times.
00:40:348 into 4, 32, 2, 3, 5, 32 and 35.
00:40:37Here it will be this much.
00:40:38Okay?
00:40:39This is our brother.
00:40:40It will be 18.
00:40:41With 18, 1 will come to 0.
00:40:43Now how much is the multiplication of 88?
00:40:45So about 2 times here.
00:40:46So this is our option close to 42.
00:40:48The option number will be answered here.
00:40:49How is my brother?
00:40:50Look at this.
00:40:51When it will cut it.
00:40:52So when this number will cut it,
00:40:54then this is our 14205.
00:40:56Something like this.
00:40:57It will cut in this much.
00:40:58You divide and see.
00:40:59It is coming by dividing this much.
00:41:01And this will be equal to the same thing.
00:41:03Whose?
00:41:04100 plus P2.
00:41:05100 plus P2.
00:41:06So we will subtract it from this.
00:41:08So my brother 42.05 percent.
00:41:10What will happen to us?
00:41:12P2 will be considered.
00:41:13What will happen to us?
00:41:15P2 will be considered.
00:41:16There is a little calculation, sir.
00:41:18There is nothing else.
00:41:19There is nothing else but calculation.
00:41:21Keep this in mind.
00:41:22And the biggest thing.
00:41:23Brother, we did not use data at all.
00:41:25Let the whole world do it.
00:41:27So let it waste time.
00:41:28She is doing.
00:41:29Why will you do?
00:41:30Brother, we have taught you to waste time.
00:41:32Tell.
00:41:36Fine.
00:41:38Come on, brother.
00:41:39Come on.
00:41:40Next, let's see here.
00:41:41What was said in question number 67?
00:41:43Read a little.
00:41:44So it was said.
00:41:45By selling an article for rupees this much.
00:41:47A man allowed 10 percent discount and earned 30 percent profit.
00:41:50If this article is sold at this much discount, what is the profit percent?
00:41:54The same question.
00:41:56Is there a need for my brother data here?
00:41:58Say no.
00:41:59Oh, man, how much are you selling?
00:42:01How much are you buying?
00:42:02What do we mean?
00:42:03We do not mean brother.
00:42:05We mean by this.
00:42:0710 percent discount.
00:42:0830 percent profit.
00:42:09So how much will be our profit at 5 percent discount?
00:42:12That's it, my brother.
00:42:13End here.
00:42:14Sir, if there is a discount, we have 10 percent.
00:42:17So how much profit are we getting?
00:42:19So the profit here is 30 percent.
00:42:22So if we make this discount here, my brother,
00:42:255 percent.
00:42:26So, my brother, will you not calculate the profit here?
00:42:29Say here.
00:42:30It will not happen.
00:42:31I would have been in your place.
00:42:32Do you know what I would have done?
00:42:33I would have written directly here in FAST.
00:42:34130 and 90 in the box.
00:42:36It will be equal.
00:42:37100 plus P2 here.
00:42:38And divided by 95.
00:42:40Solve it straight, my brother.
00:42:42And here 13 left.
00:42:4365, 6, 13, 9, 117 and 6, 123.
00:42:46And 9 in the box.
00:42:479 becomes 9.
00:42:48And it's 33, my brother.
00:42:499, 3, 27.
00:42:50Okay.
00:42:51It's 65.
00:42:52So it's 9, 9.
00:42:53I mean, 9, 6, 54.
00:42:549, 7, 3, 63.
00:42:55Which option is near 37 here?
00:42:57A little more than 37 means option number D answer will come.
00:43:00So solve the rest and see, my brother, here.
00:43:03Okay.
00:43:04We will not solve.
00:43:05We have told the way here.
00:43:06How to do it?
00:43:07The rest you have to make this question yourself.
00:43:09Because sir, we have taught you the formula.
00:43:11Okay.
00:43:12You know the formula.
00:43:13We have told the structure.
00:43:15So you will make this question yourself.
00:43:18It will not come exactly 37.
00:43:19It will come a little more than 37.
00:43:25I think you will have confusion.
00:43:27Look, brother, I will tell you.
00:43:28Come on, remove it.
00:43:29Why will you have confusion?
00:43:30Take it, I will tell you.
00:43:31Look, it's a simple thing here.
00:43:32100 plus P1 and divided by 100 minus D1.
00:43:35Take it, brother.
00:43:36Some people have a stomachache.
00:43:38No, how did you give it to us?
00:43:40You tell yourself.
00:43:41I gave you all the money.
00:43:42I want the whole solution.
00:43:43It's amazing, brother.
00:43:44It's amazing.
00:43:46Take it, brother.
00:43:47I am making it for you.
00:43:48What was said?
00:43:49Look at the P1 command.
00:43:50How much is it?
00:43:51It is 30.
00:43:52Add 30 to 100.
00:43:53How much will it be?
00:43:54130.
00:43:55We wrote it here first.
00:43:56Look at the D1 command.
00:43:57It is 10.
00:43:58You will reduce 10 to 100.
00:43:59It will be 90.
00:44:00Equal my brother.
00:44:01This will be your 100 plus P2.
00:44:02And how much is the D2 command here?
00:44:03It is 5.
00:44:04You will reduce 5 out of 100.
00:44:05It will be 95.
00:44:06Finish it, brother.
00:44:07What will happen if you multiply it?
00:44:0813 into 5.
00:44:0965.
00:44:105 in 6 hands.
00:44:11139.

00:50:569.
00:50:589.
00:51:009.
00:51:02In ICR, there is a fixed structure.
00:51:04There are not many changes in it.
00:51:06The whole game is in discount.
00:51:08People combine them and teach.
00:51:10Our teaching method is different.
00:51:12We teach profit loss first, then we teach discount.
00:51:14So, you have to be patient with me
00:51:16till the end.
00:51:18Only if you have patience till the end,
00:51:20you can learn a lot.
00:51:22If you give up in the beginning, it's over.
00:51:24Now read this question. It's an amazing question of ICR.
00:51:26Shopkeeper gains 20%
00:51:28by selling an article when he gives 30%
00:51:30discount.
00:51:32I am highlighting.
00:51:34He gains this much
00:51:36when he gives 30% discount.
00:51:38If the cost price of the article
00:51:40is increased by 20.
00:51:42If we increase the cost price
00:51:44by 20,
00:51:46and still want to earn a profit
00:51:48of 12%, then how much discount
00:51:50should he give now
00:51:52on the same market price?
00:51:54Apply the same formula twice.
00:51:56Apply the same formula twice.
00:51:58Apply the same formula twice.
00:52:00Because there are two parts of the question.
00:52:02ICR said that you are from CIGEL.
00:52:04You set small questions.
00:52:06We make you a good question.
00:52:08We teach you how to apply the same formula twice.
00:52:10The first part they gave us
00:52:12was that you use this data
00:52:14and do part no. 1.
00:52:16If there is a profit of this much
00:52:18and a discount of this much, then what will happen?
00:52:20We said, sir, understand
00:52:22about this.
00:52:24In our language, MP upon CP is fixed.
00:52:26How much is MP upon CP?
00:52:28If there is a profit, then we add.
00:52:30If there is a discount, then we subtract.
00:52:32It is fixed here.
00:52:34According to situation no. 1,
00:52:36what will happen to MP upon CP?
00:52:38It will be fixed here.
00:52:40What is our gain?
00:52:42It is 20. And what is our discount?
00:52:44It is 30.
00:52:46We will say 100 plus 20.
00:52:48You can write here.
00:52:50Which flight do I have to catch?
00:52:52Which wife is calling me to the airport?
00:52:54Let's go for a walk here.
00:52:56You can teach me easily.
00:52:58We will tell you everything easily.
00:53:00Read it here.
00:53:02If we talk here,
00:53:04we will say, sir, MP upon CP
00:53:06will be equal to
00:53:08if you add 20 to 100,
00:53:10it becomes 120.
00:53:12If you subtract 30 from 100, it becomes 70.
00:53:14It is your wish. If you want to deduct 0, then deduct.
00:53:16If you don't want to deduct,
00:53:18then don't deduct.
00:53:20It is not a problem.
00:53:22This was from part no. 1.
00:53:24If you get a discount of 30%
00:53:26on an article
00:53:28and a profit of 20%,
00:53:30what will be the relation between MP and CP?
00:53:32It will be the same.
00:53:34What will be the relation between MP and CP?
00:53:36It will be the same.
00:53:38You can remove this part.
00:53:40If there is a discount of 30% on an article
00:53:42and a profit of 20%, it is its ratio.
00:53:44Let's go to the next part.
00:53:46Understand the next part.
00:53:48If we increase its cost price
00:53:50by 20%,
00:53:52whatever its cost price is,
00:53:54if we increase it by 20%,
00:53:56and after that,
00:53:58we want a profit of 12%,
00:54:00then
00:54:02how much discount will we have to give
00:54:04on the same market price?
00:54:06Now, we will switch to part no. 2.
00:54:08Now, what will we do in part no. 2?
00:54:10We will apply the same formula
00:54:12on part no. 2.
00:54:14We will say the same thing again.
00:54:16Sir, again there is an MP
00:54:18and again there is a CP.
00:54:20Again, there is a new profit
00:54:22and again there is a new discount.
00:54:24Now, what did I say in the question?
00:54:26If my brother,
00:54:28now the same market price,
00:54:30earlier the market price was
00:54:32120, so still
00:54:34the market price is 120.
00:54:36Now, the new CP, you can say
00:54:38Sir, this is MP 2,
00:54:40CP 2, here is discount 2,
00:54:42and this is 2.
00:54:44So, if we increase the CP
00:54:46by how much percent?
00:54:48How much percent?
00:54:50So, CP of article being increased by 20,
00:54:52increase it by 20%.
00:54:54So, my brother, if you increase it by 20%,
00:54:56then tell me one thing,
00:54:58how much is 20% of 70?
00:55:00It is 14. How?
00:55:02By percentage, both are 0, 7 into 2 is 14.
00:55:04So, if you increase 14, how much will it be?
00:55:06It is 84. So, if we have the same market price,
00:55:08our CP increases by 20%,
00:55:10and after that,
00:55:12we have to earn a profit of 12%.
00:55:14So, my brother, add here 100 plus 12,
00:55:16100 plus 12, so in question,
00:55:18it is said, my brother, how much will be the discount?
00:55:20See, how to use the same formula
00:55:22in two ways?
00:55:24First, the ratio of discount
00:55:26on the first profit, now it is said,
00:55:28on the same market price,
00:55:30at a price of 20% more than this,
00:55:32if my brother, this much of profit is there,
00:55:34then how much will be the discount?
00:55:36That means, we know MP, we also know CP,
00:55:38we also know the profit,
00:55:40to get the discount. So, when in four things,
00:55:42you know, you cannot take out the fourth thing.
00:55:44Can you take it out or not?
00:55:46You can definitely take it out.
00:55:48So, now you solve this.
00:55:50You bring, my brother, solve here.
00:55:52What will you say directly?
00:55:54Sir, see here, if we cut it,
00:55:56then my brother, what will happen here?
00:55:58From 24, you will cut in 5 times,
00:56:00from 24, you will cut in 4 times.
00:56:02So, you will say here, sir, 4 in 5,
00:56:04and equal, this will be our 112.
00:56:06And how much will be divided by?
00:56:08So, my brother, 100 minus 2.
00:56:10Okay, no problem here.
00:56:12If you see, then you will multiply it by 4.
00:56:14If you multiply it by 4,
00:56:16then my brother, 4, 4, 8 will come.
00:56:18This part will go here.
00:56:20So, this will be 100 minus D2.
00:56:22Okay, and this will be equal.
00:56:24See this part. This is multiplication above
00:56:26and this is division below. So, multiplication above is this much.
00:56:28And my brother, see here, I repeat again.
00:56:30Here, if we talk about multiplication above,
00:56:32then if we multiply above,
00:56:34then 448, and if we go below
00:56:36and divide, then this much.
00:56:38If we see next,
00:56:40then 100 minus D2 is equal.
00:56:42How much will be this?
00:56:44So, you will say, sir, 896 here.
00:56:4689.6 will be this.
00:56:48Okay.
00:56:50The rule is to divide any number by 5.
00:56:52If you double it, then you have doubled it.
00:56:54And after that, leave a number and multiply by 10.
00:56:56Now, subtract 89.6 from 100.
00:56:58How much, my brother, will come?
00:57:00How much will come? Tell me quickly.
00:57:02If you subtract from 100,
00:57:04then you are here,
00:57:06you are here.
00:57:08And shopkeeper
00:57:10gained 20 percent by 30 percent
00:57:12discount, my brother, here.
00:57:14Okay. If we see here,
00:57:16then it is said
00:57:18and still want to earn a profit of 12 percent.
00:57:2424 percent.
00:57:26Oh, man, here I have made a mistake in cutting.
00:57:28I feel so.
00:57:30And the cutting is here, I made a mistake.
00:57:32There has been a little calculation mistake.
00:57:34I can't even cut it.
00:57:36From 24, I mean,
00:57:38I am thinking here.
00:57:40If you cut it from 4 to 30 times,
00:57:42and cut it from 4, then my brother,
00:57:44in 21 times, and then 4 to 30 times,
00:57:46then in 21 times, we will cut it from 3.
00:57:48You can cut it from 12.
00:57:50You can cut it from 12.
00:57:52You can cut it from 12, my brother,
00:57:54how many times, in 10 times,
00:57:56and you can cut it from 12, in 7 times.
00:57:58This is a little calculation mistake.
00:58:00You see here.
00:58:02This will be 100 minus D2.
00:58:04Okay.
00:58:06After that, what will we do here?
00:58:08It is 112.
00:58:10And if it is 112, then multiply 112 by 7.
00:58:12So if you multiply 112 by 7,
00:58:14784 will come.
00:58:16Divided by how much, my brother, 10.
00:58:18So if you look here, you will say,
00:58:20Sir, 100 minus D2
00:58:22will be equal to 78.4.
00:58:24And if you subtract 78.4 from 100,
00:58:26then my brother,
00:58:2821.6 will come.
00:58:30This will be your D2 value.
00:58:32Option number C
00:58:34will be your correct answer.
00:58:36Option number C
00:58:38will be our correct answer.
00:58:40So a great question of ICAR,
00:58:42where you were given a good combination.
00:58:44Between whom?
00:58:46In the question, it was said that
00:58:48if there is so much profit and so much discount,
00:58:50then you take out your ratio.
00:58:52At the same market price,
00:58:54at a price of more than 20%,
00:58:56if there is so much profit,
00:58:58then you take out your ratio.
00:59:00Did you understand the thing?
00:59:02So you had to apply the same concept twice.
00:59:04You had to apply the same formula twice
00:59:06and get the answer of your question.
00:59:08Let's see the next question.
00:59:10A great question of IBACIO.
00:59:12What was said?
00:59:14He sells an item by giving 25% discount
00:59:16on its market price
00:59:18and still gains this much.
00:59:20If the cost price of the item is decreased by this much
00:59:22and he sells by allowing this much
00:59:24percent discount on same,
00:59:26then he gains percent.
00:59:28It is the same question, my brother.
00:59:30It means that both are brothers.
00:59:32This question and this question,
00:59:34both are brothers.
00:59:36The same examiner has also set this
00:59:38in ICAR.
00:59:40What did he do in ICAR?
00:59:42He asked for the discount by giving the profit
00:59:44in ICAR.
00:59:46What did he do in ICAR?
00:59:48He asked for the profit by giving the discount
00:59:50in ICAR.
00:59:52There is no problem.
00:59:54We will solve part no. 1 first.
00:59:56What is part no. 1?
00:59:58If a shopkeeper gives a discount of 25%,
01:00:00then what is the profit?
01:00:02It is 35%.
01:00:04We will just take out the ratio from here.
01:00:06We will just take out the ratio from here.
01:00:08It is better to look at this question
01:00:10so that we can understand it better.
01:00:12He gives a discount of this much
01:00:14on a given item,
01:00:16that is, this part.
01:00:18What will you say here?
01:00:20You will say that the CP in MP upon
01:00:22is equal to
01:00:24100 plus profit
01:00:26divided by 100 minus
01:00:28discount.
01:00:30If you look here,
01:00:32what will be the value of MP upon CP?
01:00:34What will be the value of MP upon CP?
01:00:36Add the profit and reduce the discount.
01:00:38If you look here,
01:00:40what is the discount?
01:00:42It is 25%.
01:00:44If you subtract,
01:00:46it will be 75%.
01:00:48After that,
01:00:50what is the gain?
01:00:52It is 35%.
01:00:54If you add 35 to 100,
01:00:56it will be this much.
01:00:58If we can see from 5,
01:01:00then we will deduct from 5.
01:01:02If we deduct from 5,
01:01:04what will we say here?
01:01:06If you deduct from 5,
01:01:08it will be deducted from 5 in 2 times.
01:01:10After that, it will be deducted in 7 times.
01:01:12Or you can deduct from 15.
01:01:14How many times will it be deducted from 15?
01:01:16It will be deducted from 15 in 9 times.
01:01:18And it will be deducted from 15 in 5 times.
01:01:209 divided by 5 is
01:01:229 divided by 5,
01:01:24so let it be 9 divided by 5.
01:01:26We can write 9 divided by 5 as 90 divided by 50
01:01:28and 900 divided by 500.
01:01:30This is our own wish.
01:01:32Nobody can stop us in this.
01:01:34If I want to take the value of
01:01:36MP and CP tomorrow,
01:01:38then I will make it 90 divided by 50.
01:01:40Why? Because if I have to increase
01:01:42some percentage, then it will be easier.
01:01:44And if I have to reduce some percentage,
01:01:46then it will be easier.
01:01:48It is difficult to add in 5 and deduct in 5.
01:01:50My brother, it is easier to deduct
01:01:52any percentage of 50.
01:01:54So, even if it was in some other value,
01:01:56we changed it to some other value.
01:01:58This is the art of the ratio.
01:02:00Let me tell you the mistake of many children.
01:02:02They solve
01:02:04135 divided by 75 as data.
01:02:06In that case, their calculation
01:02:08increases.
01:02:10And they don't understand how to solve it.
01:02:12I say you cut them.
01:02:149 divided by 5 came and
01:02:16make 9 divided by 5 as 90 divided by 50.
01:02:18What will happen with this? Calculation will be easy.
01:02:20It will be beneficial to add and subtract.
01:02:22So, this first part is completed
01:02:24from here to here.
01:02:26There is no need for this.
01:02:28Now let's go to the second part.
01:02:30Let's decrease the cost price
01:02:32by 10%.
01:02:34After that, let's sell it
01:02:36at the same market price
01:02:38and the same discount.
01:02:40So, what will be the percentage of our profit?
01:02:44Here again,
01:02:46we made another calculation mistake.
01:02:52If we subtract 35 out of 100,
01:02:54we will get 65.
01:02:56See, we made a mistake.
01:02:58We made a mistake here.
01:03:00If we reduce the discount,
01:03:02we will get 65.
01:03:08Let me tell you again.
01:03:10No problem, I will tell you again.
01:03:18I will tell you again.
01:03:20See this question.
01:03:24Let me change the battery.
01:03:28...
01:03:30...
01:03:32...
01:03:34...
01:03:36...
01:03:38...
01:03:40...
01:03:42...
01:03:44...
01:03:46...
01:03:48...
01:03:50...
01:03:52We were going right.
01:03:54It was right.
01:03:56If there is a profit of 35,
01:03:58then we will add 35.
01:04:00If there is a discount,
01:04:02then we will add 35.
01:04:04If there is a discount of 25,
01:04:06then we will reduce it.
01:04:08If there is a market price,
01:04:10then we will reduce it.
01:04:12You create a lot of confusion.
01:04:14It was written well.
01:04:16I had to erase it.
01:04:18No problem,
01:04:20I will tell you again.
01:04:22It was a good question.
01:04:24You disturbed me.
01:04:26There are some kids.
01:04:28They understand everything.
01:04:30That's why I write a line.
01:04:32I did not write this part.
01:04:34I wrote directly.
01:04:36I wrote directly.
01:04:38I got confused.
01:04:40God bless you.
01:04:42Come and read.
01:04:44Let me repeat it again.
01:04:46This question is number 70.
01:04:48This is also a photocopy.
01:04:50This is also a photocopy.
01:04:52It is also said in the Quran
01:04:54that if a shopkeeper sells
01:04:56something at a discount of 25%,
01:04:58then he gets a profit of 35%.
01:05:00If you reduce your cost price
01:05:02by 10% and then
01:05:04give a discount of 35.5%,
01:05:06then what will be the gain here?
01:05:08It was the same thing here.
01:05:10There is no difference here.
01:05:12If you look here,
01:05:14as we wrote earlier,
01:05:16look at this part.
01:05:18This is the whole part.
01:05:20We will solve this part.
01:05:22We will solve this part.
01:05:24You disturb me a lot.
01:05:26If you look here,
01:05:28the CP in MP
01:05:30will be equal to
01:05:32100 plus profit
01:05:34and 100 minus
01:05:36discount.
01:05:38It's a simple thing.
01:05:40If we look here,
01:05:42the CP in MP
01:05:44will be equal to
01:05:46profit plus discount.
01:05:48This is your profit.
01:05:50If you add it here,
01:05:52it will be equal to 35.
01:05:54If you add it here,
01:05:56it will be equal to 25.
01:05:58If you add it here,
01:06:00it will be equal to 25.
01:06:02If you add it here,
01:06:04it will be equal to 135.
01:06:06If you add it here,
01:06:08it will be equal to 75.
01:06:10If you add it here,
01:06:12it will be equal to 75.
01:06:14If you add it here,
01:06:16you will get 95.
01:06:18You will get 95.
01:06:20As we are telling you,
01:06:22If you want to
01:06:24increase 10% in this,
01:06:26the work will be very difficult.
01:06:28You can make
01:06:309.5 into 90.
01:06:329.5 into 90.
01:06:34It is not a problem.
01:06:36Artistic Empire can be
01:06:38done.
01:06:40You can convert it.
01:06:42It's not a problem.
01:06:44now as per the question
01:06:46now as per the question
01:06:48that is the article
01:06:50if you want to change
01:06:52then you can see here
01:06:54now as per the question
01:06:56you can fill here
01:06:58now the first part is over
01:07:00now see the second part
01:07:02if we decrease the cost price
01:07:04read here
01:07:06if we decrease the cost price
01:07:08by 10%
01:07:10what we do to decrease the cost price
01:07:12from how much? from 10%
01:07:14so this is your cp 50
01:07:16decrease it
01:07:18decrease your cost price by 10%
01:07:20decrease your cost price by 10%
01:07:22that means 10% of this is 5
01:07:2410% of 50 is 5
01:07:26in this my brother
01:07:28we will decrease 10%
01:07:30so how much will come? 45
01:07:32so we decreased here
01:07:34after that
01:07:36and he sell it by allowing a
01:07:38this much percent discount
01:07:40so the discount
01:07:42out of 100
01:07:44is 37.5
01:07:46so here we will write the discount
01:07:48on the same market price
01:07:50what will be the market price?
01:07:52here it is 90
01:07:54so how much will be here?
01:07:56it will be 90
01:07:58so what will be the gain percentage?
01:08:00100 plus P2
01:08:02how many times did he sell it?
01:08:042 times
01:08:06now here it is 2 into
01:08:08if you decrease it from 100
01:08:10it will be 62.5
01:08:1262.5 will be equal to
01:08:14100 plus P2
01:08:16and if you see here
01:08:1862.5 double is 125
01:08:20how much is it?
01:08:22125 is equal to
01:08:24100 plus P2
01:08:26and this will be 100 plus P2
01:08:28so if we decrease 100 from 125
01:08:30then 25% profit will come
01:08:32and this will be the right answer
01:08:34option number A
01:08:36so here
01:08:38the right answer will come
01:08:40so we have understood
01:08:42so we have to keep this in mind
01:08:44that the last two questions
01:08:46both of them were brothers
01:08:48one was of CRPF
01:08:50and the other was of this
01:08:52so these are good level questions
01:08:54think where did we start
01:08:56so the first question we started
01:08:58was to find the ratio
01:09:00and where are we ending today
01:09:02so I always say that I will start
01:09:04so this is the real zero to hero
01:09:06where you can understand
01:09:08everything about zero level
01:09:10and hero level
01:09:12now the remaining questions
01:09:14from 71 to
01:09:1684
01:09:18and the remaining
01:09:20we have to apply double class
01:09:22or triple class
01:09:24or whatever we have to do
01:09:26we will finish it tomorrow
01:09:28so don't worry
01:09:30we will cover all the questions
01:09:32ok brother
