Similarly, if you invest Rs 80,000, you will get Rs 97,791 on maturity. The interest will be Rs 17,791 at a 6.75 per cent interest rate.
If you invest Rs 1,20,000, the maturity amount will be Rs 1,65,650 with Rs 45,650 interest at a 6.50 per cent interest rate.
Similarly, if you invest Rs 1,50,000, you will get Rs 2,07,063 at an interest rate of 6.50 per cent yearly. The interest amount will be Rs 57,063.
