Question

At what rate of simple interest per annum will a sum become 7/4 of itself in 4 years

Answer 1

Hi..!

Let the sum be Rs x .

Then amount = 7/4 of x = Rs 7x/4

Thus , SI = A - P = Rs 3x/4

Time = 4 years .

Using formula , R = Si * 100 / P * T = 3x * 100 / 4 * 4 * x = 75/4 = 18.75% p.a (answer)

Thanks...!
