Question
A man invested a certain amount of sum at 12.5%
per annum simple interest and earned an interest of Rs. 2700 after 3 years. If the same amount is invested at 20% per annum compound interest, compounded annually for two years then the interest would be:Solution
Let the certain sum of money be Rs. P
So, P × 0.125 × 3 = 2700
So, P = Rs. 7200
Desired interest = [(1.2)2 – 1] × 7200 = Rs. 3168
