A pension fund pays Rs 10,000 at the end of each year for 3 years. Using an effective annual interest rate of 10%, what is the present value of these payments?

The present value is Rs 24,868.52. Each year-end payment of Rs 10,000 is discounted at 10%, giving 10,000 times the annuity-immediate factor 2.486852. Treating payments as advance, or accumulating them, would give different values.

  2. BRs 24,868.52Correct
  3. CRs 27,355.37
  4. DRs 30,000.00
  5. Rs 33,100.00

Explanation

PV = 10,000 × a3 at 10% = 10,000 × (0.909091 + 0.826446 + 0.751315) = 10,000 × 2.486852 = Rs 24,868.52. Rs 27,355.37 treats the payments as made in advance. Rs 33,100.00 is the accumulated value at time 3, not the present value.
