Question
A man invested a certain amount of sum at 18% per
annum simple interest and earned an interest of Rs 2700 after 6 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 × 0.18 × 6 = 2700
So, P = Rs. 2500
Desired interest = [(1.20)2 – 1] × 2500 = Rs. 1100

(75 + 0.25 × 10) × 4 = ?2 - 14
26% of 650 + 15% of 660 – 26% of 450 = ?
115% of 40 + 3 × 4 = ? × 11 – 8
