A person deposited Rs. 2500 at the starting of each year at the rate of 20% per annum compounded annually. Then find the total amount at the end of 3rd year.

Rs. 10920

Principal at starting of 1st year = Rs.2500

Amount at the end of 1st year = 2500 × 120% = Rs.3000

Principal at starting of 2nd year = 3000 + 2500 = Rs.5500

Amount at the end of 2nd year = 5500 × 120% = Rs.6600

Principal at starting of 2nd year = 6600 + 2500 = Rs.9100

Amount at the end of 2nd year = 9100 × 120% = 10920
