The amount on a sum of ₹2,400 at 20%

Principal P=₹2400
Rate R=20% per annum
Time T=2 years (compounded annually)

Compound Amount formula:

$A = P\left(1+\frac{R}{100}\right)^T$

Substitute the values:

$A = 2400\left(1+\frac{20}{100}\right)^2$

$A = 2400(1.2)^2$

$A = 2400 \times 1.44$

A = 3456

✅ Correct Answer: ₹3,456
