  1. ₹6,500
  2. ₹5,500
  3. ₹6,050 Correct answer.
  4. ₹6,000

Explanation

For compound interest, A = P(1 + r/100)^n. Here P = ₹5,000, r = 10% and n = 2, so A = 5000 × (1.1)² = 5000 × 1.21 = ₹6,050. Simple interest for two years would give ₹6,000, which is less because interest is not compounded.
