Correct Answer: $22 \frac{2}{9}$%
Solution : Let P be the principal and R be the rate of interest. Total amount = 3P Simple interest, SI = 3P – P = 2P Term, n = 9 years So, SI = $\frac{PnR}{100}$ ⇒ 2P = $\frac{P×9×R}{100}$ ⇒ R = $\frac{200}{9}$ = $22\frac{2}{9}$% Hence, the correct answer is $22\frac{2}{9}$%.
