More than 10 lakh interest on an investment of 5 lakhs

If you invest 5 lakhs in this FD, then according to the interest rate of 7.5 percent, you will get 2,24,974 rupees interest on this amount in 5 years. In this way, the total amount will be 7,24,974 rupees. But if you extend this scheme for 5 years, then you will get 5,51,175 rupees only as interest and after 10 years your total amount will be 10,51,175 rupees. You will have to extend it one more time before it matures. In such a situation, in the 15th year, you will get Rs 10,24,149 only as interest.
