A sum of ₹2,000 is invested for 3 years at 5% per annum. Find the difference between the compound interest and the simple interest (in ₹), if the interest is compounded annually.
15.25
SI for 3 years = 2000 × 5 × 3 ÷ 100 = ₹300.
CI: amount = 2000 × (1.05)3 = 2000 × 1.157625 = ₹2315.25, so CI = ₹315.25.
Difference = 315.25 − 300 = 15.25.
Hence, the answer is 15.25.
