A sum of ₹1,00,000 is invested at 12% per annum for one year. Interest is compounded half-yearly. What is the effective annual rate (EAR) and the maturity value?

The effective annual rate is 12.36% and the maturity value is ₹1,12,360. Half-yearly compounding applies 6% twice, so 1.06 squared equals 1.1236. This exceeds the 12% nominal rate because interest in the first half earns further interest.

  1. A12.00%; ₹1,12,000
  2. B12.36%; ₹1,12,360Correct
  3. C12.68%; ₹1,12,680
  4. D6.00%; ₹1,06,000

Explanation

Half-yearly rate = 6%. Maturity = 1,00,000 × (1.06)^2 = 1,00,000 × 1.1236 = ₹1,12,360, so EAR = 12.36%. The 12.68% option corresponds to quarterly compounding (1.03^4 = 1.1255 is actually 12.55%), so it is wrong anyway; 12%/₹1,12,000 ignores compounding.
