Question

6. Simple interest on a certain sum is 16/25

of the sum. Find the rate percent and the

time if both are numerically equal.​

Answer 1

Step-by-step explanation:

Let sum = x. Then, S.I = (16x)/25

Let rate = R % and time = R years.

(x xx R xx R)/(100)

= (16x)/25 or R^2 = (1600)/25 R = 40/5 = 8`

Rate = 8% and Time = 8 years.
