Question : The compound interest (compounding annually) on a certain sum for 2 years at the rate of 60% per annum is INR 6240. What will be the simple interest on the same sum for 3 years at the same rate of interest?
Option 1: INR 6800
Option 2: INR 7200
Option 3: INR 7100
Option 4: INR 6500
Correct Answer: INR 7200
Solution : Rate, $R$ = 60% Term, $n$ = 2 years Compound interest = INR 6240 Let $P$ be the principal sum. When compounded annually, Compound interest = $P(1+\frac{R}{100})^n - P$ $⇒6240 = P(1+\frac{60}{100})^2 - P$ $⇒6240 = P(1+\frac{3}{5})^2-P$ $⇒6240 = P(\frac{8^2}{5^2})-P$ $⇒6240 = P(\frac{64}{25}-1)$ $⇒6240
