At the beginning of the 1974/75 school year a man invested 2000 in a bank at 12and half% compound interest if he with 650 at the end of each school fees how much did he have left at beginning of the 1978/79

pls work it for me in full explanation

From 1974/1975 to 1978/1979 is 4years. So find the compound interest for each year for 4years and at the end of each minus 650 from it. Then find the compound interest for the remainder of each year. Upto the 4th year then the remainder becomes your answer (74.2)
