Question

A man leaves Rs 1,15,500; 1/3 of it he leaves to his wife, 2/7 of the rest to each of his two daughters and the remaining to his son. How much does his son get?

Answer 1

1/3 of 115500= 38500
Remaining= 115500-38500= 77000
2/7 of 77000= 22000
He gives 22000 to each of his two daughters, so total= 44000
Remaining= 77000-44000= 33000
Therefore the son gets Rs. 33000. 
To check: Wife's share+ both the daughters' share+ son's share
              =38500+44000+33000
              =115500
