Question : At what annual rate (rounded off to the nearest integer) of simple interest will a sum of money become five times its initial value in 18 years?
Option 1: 18%
Option 2: 20%
Option 3: 22%
Option 4: 24%
Correct Answer: 22%
Solution : Given. Time = 18 years Let the principal be $x$. The sum of money after 18 years = $5x$ Simple interest = $5x-x=4x$ Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ $⇒4x=\frac{x× \text{Rate}×18}{100}$ $\therefore$ Rate = $\frac{400}{18}=22.22\approx 22$% Hence, the correct answer is 22%.
