Answer 1

Interpretation:

The simple interest of a certain sum of money for 5 years at 8% is ₹200 less than the simple interest on the same sum for 3 years and 4 months at 18%. Find the sum of money.

Let the sum of money be x
first case:
interest = x(.08)(5) = .4x
second case: 3 years and 4 months = 10/3 years
interest = x(.18)(10/3) = .6x

then .6x - .4x = 200
.2x = 200
x = 1000
