21UCR304: Business Calculus and Financial Computation

Mr. Suresh, aged 55, purchases a life annuity policy from Life Insurance Corporation of India by investing à·¹8,00,000. The policy provides an annual payment of à·¹75,000 at the end of each year as long as he survives. The annual effective interest rate is 5%.

The probabilities that Mr. Suresh survives for the next 4 years are given below:

<t****/td>

Year Survival Probability
0.97
2 0.94
3 0.90
4 0.85

At the same time, he also purchases a life insurance policy with a sum assured of à·¹12,00,000. The probability of death within one year is 0.03.

The present value of the annuity payments is given by:

PV=\sum_{t=1}^{4}\frac{75000\times p_t}{(1.05)^t}

and the expected insurance claim is:

E(X)=1200000\times0.03

Questions

  1. Calculate the expected present value of the life annuity.

  2. Find the expected insurance claim amount.

  3. Determine whether the annuity investment is beneficial for Mr. Suresh.

  4. Explain the role of probability in contingent payments and life insurance.
