Mohan distributed his total assets to his wife, three sons, two daughters and five grandchildren in such a way that each grandchild got one-eighth of each son or one-tenth of each daughter. His wife got 40 per cent of the total share of his sons and daughters together. If each daughter received asset of worth Rs. 1.25 lakh. what was the total worth of the assets received by his wife and his five grandchildren together ?

One eighth of the amount received by each son is equal to one tenth the amount received by each daughter.

As each daughter received Rs. 1.25 lakhs, it means that each son received 1.25*8/10 = 1 lakh.
So, the total amount received by 3 sons and 2 daughters is 3*1 + 2*1.25 = 5.5 lakhs

Hence, the amount received by the wife is 40%*5.5 = 2.2 lakhs

Amount received by each grandson is 1/10th the amount received by each daughter i.e 0.125 lakhs
Hence, the total amount received by 5 grandchildren is 5*0.125 = 0.625 lakhs

So, total received by wife and grandchildren is 2.2 + 0.625 = 2.825 lakhs = 2,82,500
