Now, your task is to cut that block into 4 pieces such that only using those 4 pieces

and the two-way balancing pan, you can measure any weight from 1 kg to 38 kg.

(You should be able to measure any weight like 1 kg, 2 kg, 3 kg up to 38 kg).

a) Explain your approach and the logic involved in finding the same.

b) Represent on a pan balance how you will measure 11 kg, 32 kg, 35 kg
