✨Step by Step✨

Let the principal amount be Rs. 100

Simple interest should be three fourth (3/4th) of the principal.

So,

the simple interest = (100×3)/4= Rs. 75

So,

P = Rs. 100; Rate of Interest = 6 % Time = ? Simple Interest = Rs. 75

Simple Interest = (P×R×T)/100

→ 75 = (100×T)/100

75×100=600T

→ T = 7500/600

→ T = 25/2 or 12 years and 6 months

So, in 12 years and 6 months the simple interest on a certain principal will be three-fourth of that principal @ 6% per annum.
