Question

Q. In what time will the simple interest on a certain sum of money at 25/4 % per annum be 3/8 th of itself?​

Answer 1

Answer:

6 YEARS

Step-by-step explanation:

Let the sum of money be Rs P

So, the S.I will be Rs. 3P/8

Given, the rate of interest per annum is Rs. 25/4

We know that,

S.I = PRT/100

or, 3P/8 = Px25xT/4x100

or, T = 3Px400/8x25P

or, T= 6

Therefore, the required time is 6 years.
