Question
A man invested a certain amount of sum at 10% per
annum simple interest and earned an interest of Rs. 3000 after 5 years. If the same amount is invested at 25% 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 × 0.10 × 5 = 3000
So, P = Rs. 6000
Desired interest = [(1.25)2 – 1] × 6000 = Rs. 3375
