●Let income be 100
\ Sum given to elder son
= 20% of 100 = 20
Remaining Sum = Rs. 80
Sum given to younger son
= 30% of 80 = 24
Remaining sum
= Rs. (80 – 24) = Rs. 56
Sum given to the trust
= 10% of 56 = 5.6
Remaining sum
= (56 – 5.6) = 50.4
When 50.4 remains, total income
= 100
When 10080 remains, total income
= 100×10080/50.4 = 20000
