Question

Simple interest on a certain sum is 16/25 of the sum. Find the rate per cent and the time if both are numerically equal.
(i want full answer with working)

Answer 1

Answer:

Let sum = X. Then S.I = 16x/25

Let rate = R% and Time = R years.

Therefore, (x * R * R)/100 = 16x/25 => R = 40/5 = 8
