Question
The interest earned when a sum is invested at simple
interest of 16% p.a., for 3 years, is Rs. 2400. What will be the total amount received after 2 years on investing the same sum at compound interest (compounded annually) of 10% interest p.a.?Solution
Let the sum invested = Rs. Y According to the question, (Y × 3 × 16) ÷ 100 = 2400 So, Y = (2400/0.48) = 5000 So, required amount received = 5000(1 + 10/100)2 = 5000(11/10)2 = Rs. 6050

- 27.99² - 40.02% of 419.99 + √3135.99 = ? X 5.99
(2.02/16.89) of 1512.98 + (5.96/18.89) of 1861.78 + (1.95/3.02) of 723.11 = ? × 7.96
? = (5.8)2 + (8.9)2 + (4.7) 2 + 24.7% of 20
? = 54.89 × 270.08 ÷ 135.17 + 464.35 ÷ 29.03
72.8% of (215.69 + 189.38) - 5.97² + (3.01 of 7.8) = ? of (64.02 - 38.95)
