The amount on a sum of ₹3,300 at 10%

Given: Principal P = ₹3300,
Rate  R = 10% per annum,
Time  T = 2  years
Compound Interest Formula:  A = P $ (1 + \frac{R}{100})^T $
$ A = 3300 \left(1 + \frac{10}{100}\right)^2 $
$ A = 3300 \left(1 + 0.1\right)^2 = 3300 (1.1)^2 $
$ A = 3300 \times 1.21 = 3993 $

Answer: ₹3,993 ✅
