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 %
Hope it helps

Answer:
12.66%
Step-by-step explanation:
amount = principal + interest
7/4 = 1 + X
7/4 - 1 = X
3/4 = X
R% = I * 100/PT
R% = 3/4 * 100/1 * 6
R% = 75/6
R% = 12.66
