Interest on fixed deposit was received for six months. The money on the fixed deposit was invested on 1 June 20.22 for a period of 5 years.
Interest on fixed deposit is 720
Assuming that the interest on the fixed deposit is received semi-annually, the total interest earned on the fixed deposit for six months would be half of the annual interest. Therefore, the annual interest earned on the fixed deposit is 720 * 2 = 1440.
If the interest on the fixed deposit is 1440 annually, then the total interest earned over 5 years would be 1440 * 5 = 7200.
Therefore, the total interest earned on the fixed deposit over the 5-year period is 7200.
