Question

Simple Interest on a certain sum is 16 upon 25 of the sum. Find the rate per cent and the time if both are numerically equal.​

Answer 1

Answer:

Rate percent = 8%

Time= 8 years

Step-by-step explanation:

Let the principal or sum be X

then S.I = 16x/25

according to question,

Rate percent = Time

so,

let rate and time be y

S.I = P ×R×T÷ 100

16x/25 = x × y × y ÷ 100

1600/25 = y²

64 =  y²

y = 8

Rate percent = 8%

Time= 8 years
