Answer 1

Answer:

Solution:

If you look at the question, initially person had some rupees, Let us assume he had a rupees.

Step 1: He gave 20% of his income to his elder son. ( 20% decrease in income, so M.F.=0.8 )

Remaining Amount = 0.8a ( M.F x Initial amount )

Step 2:He gave 30% of remaining to younger son (30% decrease in income,so M.F.= 0.7 )

Remaining Amount = 0.7 X 0.8 a

Step 3: Then he gave 10% of the balance to a trust (10% decrease in income, so M.F.=0.9 )

Remaining income= 0.9 x 0.7 x 0.8 a

Remaining income= 0.504 a

Now it is given that final remaining amount = 10800

0.504 a = 10800

a = 10800/ 0.504
