You just got a new job and are trying to decide whether to begin saving for retirement now or in a few years. You are 25 years old now and expect to retire when you are 65. You feel you can save 300 rupees a month toward retirement. How much will have at retirement, if you start saving today, provided that the interest rate is 6% per annum. Also calculate the sum you will have at retirement if you start saving 300 rupees every month, but only after two years from now at the same interest rate.
