Question

simple interest on a certain sum is 16/25 of the sum. find the time if rate percent and time are equal


please tell step by step plz​

Answer 1

Simple interest (si)=16/25 of the sum

let the sum= x

So, the si=16x/25

Time(t)=rate of interest(r)

let them=y

$as \: we \: know \\ si = \frac{p \times r \times t}{100} \\ threfore \\ \frac{16x}{25} = \frac{x \times y \times y}{100} \\ \frac{16x}{25} \times 100 = x {y}^{2} \\ \frac{64x}{x} = {y}^{2} \\ y = \sqrt{64} \\ y = 8$

Therefore, Time = 8 years
