Question
A sum of money at a specific
annual simple interest rate grows to Rs. 2900 in 3 years and Rs. 3500 in 5 years. Calculate the interest earned when this same amount is invested at a rate of 25% p.a. compounded annually for 2 years.Solution
ATQ,
Simple interest earned in two years = 3500 – 2900 = Rs. 600 Simple interest earned in 1 year = Rs. 300 So, sum invested = 2900 – 3 × 300 = 2900 – 900 = Rs. 2000 Desired interest = [(1.25)2 – 1] × 2000 = 0.5625 × 2000 = Rs.1125
15.63% of 174.99 + √? = 139.98% of 24.98
(32.18% of 2399.89 - √624 × 26.25) % of 149.79 = ?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
? = 685.24 + 1024.97 – 9.992
? = 782.24 + 1243.97 – 19.992
20.132 ÷ 62.5% of 11.16 = ? + 5109.21
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
[34.01 × 18.98 – 12 × √576.03 – 198] ÷ 3.95 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
?% of 399.99 + 139.99 ÷ 6.99 = 59.99% of 559.99 + 41.09 X 15.99
