Mr. Nair invested Rs 1,00,000, which grew to Rs 1,33,100 after 3 years with no interim withdrawals. What is the compound annual growth rate (CAGR)?

The CAGR is 10%. Dividing the final value by the initial value gives 1.331, and its cube root is 1.10. Simple averaging of the 33.1% total gain gives about 11%, which ignores compounding and is therefore incorrect.

  1. A11.0%
  2. B10.0%Correct
  3. C9.0%
  4. D11.1%

Explanation

CAGR = (1,33,100/1,00,000)^(1/3) - 1 = (1.331)^(1/3) - 1 = 1.10 - 1 = 10%. Check: 1.1^3 = 1.331. The 11.0% option is wrong as it takes the simple average of 33.1%/3 = 11.03%.
