Question

In how much time would the simple interest on a certain sum be one- eighth of the
principal at 10 % per annum?​

Answer 1

Answer:

1 (1/4) years i.e 1 year 3 months.

Step-by-step explanation:

Let the sum of money be Rs P

So, the S.I will be Rs P/8

Given, the rate of interest per annum is 10%

we know that,

S.I = PRT/100

or, P/8=Px10xT/100

or, T= 10P/8P

or, T= 5/4

or, T = 1 whole 1/4

or, T= 1year 3months.

Therefore, the required time is 1year 3months.
