What will be the compound interest (compounding annually) on a sum of Rs. 9000 at the rate of 32 percent per annum for 2 years?

Correct option is D

Given:
Principal (P) = Rs. 9000
Rate (R) = 32%
Time (T) = 2 years
Formula Used:
​$$\text {Compound Interest} = P(1 + \frac R{100})^T - P$$​​
Solution:
​$$CI = 9000 \times (1 + \frac{32}{100})^2 - 9000\\ CI = 9000 \times (1.32)^2 - 9000\\CI = 9000 \times 1.7424 - 9000 = 15681.6 - 9000 = Rs. 6681.6\\\text{Thus, the compound interest is Rs. 6681.6.}$$​​
