The Correct Option is A
Solution and Explanation
Let the amount invested by Bimal be Rs. P.
Given that the interest incomes for both are equal. Therefore,
\(\left[12000\left(1+\frac{8}{100}\right)−12000\right]+[10000\left(1+\frac{3}{100}\right)^2−10000]=P×\frac{7.5}{100}\)
Solving for P, we get\( P=Rs. 20920.\)
