Question
Simple interest and compound interest (compounded
annually) earned on a sum at the end of 2 years at a certain rate of interest p.a. are Rs. 1450 and Rs. 1624 respectively. Find the rate of interest.Solution
Simple interest for 1 year = 1450/2 = Rs. 725 Difference between compound Interest and Simple Interest for 2 years = 1624 – 1450 = Rs. 174 Desired rate = 174/725 × 100 = 24%
70.008% of 399.98 + ?% of 399.999 = 80.105% of 599.998
(278% of 695) ÷ 543 =?

- 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 = ?
