Question

₹ 1200 is invested at 8% simple interest per annum. In how much time will it double itself? ​

Answer 1

Answer:

Given P = 1200, R= 8% , Amount = 1200+1200 = 2400,

We Know that SI = PRTI

We Know that SI = A -P.

A - P = PRT/100

2400 - 1200 = 1200 *8* T/100

1200= 96T

T= 1200/96 = 12.5 years
