A man invested a certain amount of sum at 12.5% per
annum simple interest and earned an interest of Rs.2200 after 4 years. If the same amount is invested at 10% per annum compound interest, compounded annually for two years, then find the interest.Solution
Let the certain sum of money be Rs.P. So, P x 0.125 x 4 = 2200 => P = Rs.4400 Desired interest = [(1.1)2 – 1] x 4400 = Rs.924
