Explanation

CI - SI for 3 years at 5% on Rs. 2000: Formula is P * r^2 * (r+3) / 100^3 = 2000 * 25 * 8 / 1000000 = 2000 * 200 / 1000000 = 400000 / 1000000 = 0.4, but wait - let me recalculate: 2000 * (5/100)^2 * (305/100) = 2000 * 0.0025 * 3.05 = 15.25. The difference between CI and SI for 3 years follows this specific pattern.
