Determining The Object Mass Using Hooke's Law | Mechanical Properties of Solid | 11th Class Physics

A spring and load 1 with mass 8 Kg attached vertically. The spring length is 5.25 centimeters. When load 2 is added to the system. The spring length is increased to 6.1 cm. When load 1 is taken from the system. The length of the spring changes to 4.85 . The question is, what is the mass of load 2?
