Question
A man deposited Rs. 7000 at 10% compound interest,
compounded annually while Rs. 6500 at 13% simple interest per annum. What will be the difference between the compound interest and the simple interest earned by him after 3 years?Solution
Compound interest earned by the man in 3 years = 7000 × {(1 + 10/100)3 – 1)} = 7000 × 0.331 = Rs. 2317 Simple interest earned by the man in 3 years = 6500 × 0.13 × 3 = Rs. 2535 Required difference = 2535 – 2317 = Rs. 218
70.008% of 399.98 + ?% of 399.999 = 80.105% of 599.998
(278% of 695) ÷ 543 =?
A certain sum of money invested at R% p.a. fetches a compound interest (compounded annually) of 1620 and simple interest of Rs.1500 at the end of 2 year...
- 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.)
(11.99)2 + 171.16 + (3.33) 2 = ?2Â
(21.02%  of 600.15 ) × 14.95 = ? 2 + 29.99 × 3456 ÷ 1152
20% of 80 × 26% of 65 = ?
(0.89 3 + 1.64 3 +2.76 3 ) ÷ 5.89 = ?
