The future value of an ordinary annuity of ₹20,000 per year for 2 years at 10% per annum compounded annually is ₹42,000. What would be the future value at the end of 2 years if the same payments were made at the beginning of each year (annuity due)?

The future value is ₹46,200. An annuity due makes each payment one year earlier, so every payment earns one extra year of interest. The ordinary annuity value of ₹42,000 is therefore multiplied by 1.10, giving ₹46,200.

  2. B₹46,200Correct
  3. C₹37,800
  4. D₹38,182

Explanation

Each payment of an annuity due earns interest for one more year than in an ordinary annuity, so FV(due) = FV(ordinary) × (1 + i) = 42,000 × 1.10 = ₹46,200. Check: 20,000 × 1.21 + 20,000 × 1.10 = 24,200 + 22,000 = 46,200. Adding only ₹2,000 (10% on one payment) ignores interest on the whole series.
