If the rate of interest is 5%, then what would be the difference between compound interest and simple interest received on ₹ 10,000 (each) after 3 years from now ?

SI = 10000 × 5 × 3/100 = ₹1500. CI = 10000 × [(1.05)³ − 1] = 10000 × (1.157625 − 1) = 10000 × 0.157625 = ₹1576.25. Difference = 1576.25 − 1500 = ₹76.25. Wait, that gives option (c). Re-examining: CI − SI for 3 years at 5% on ₹10000 = 10000 × [(1.05)³ − 1 − 0.15] = 10000 × 0.007625 = ₹76.25. The correct answer is ₹76.25 (option c).
