Question

8. At what rate of interest will the simple interest be half of the principal in 5 years?​

Answer 1

Answer:

The answer is 10%

Proof :-

Let,

P = 2000

N = 5

S.I. = 1000

S.I. = P x N x R/100

1000 = 2000 x 5 x R/100

1000 = 10000 x R/100

1000 = 100 x R

1000/100 = R

R = 10

Therefore, rate of interest is 10%
