Question

a sum of money become 7 by 4 of itself in 6 year at the certain rate of interest find the rate of interest​

Answer 1

Answer:

It's given that the sum becomes 7/4 of itself which is the total amount.

So let the P = x

Amount = 7/4 * x

S.I = 7x/4 - x = 3x /4

S.i = P×R×T/100

3x/4 = x × R ×6/100

3×100/4×6 = R

R= 13.2 %
