Question
What will be the compound interest earned on a sum in
two years? I. The simple interest on the same amount at the same rate of interest in two years is Rs. 800. II. The amount becomes more than double at compound interest in 10 years. III. The simple interest on the same amount at the same rate of interest in three years is Rs. 1,200.Solution
From (I) & (III), SI for 1 year = Rs. 400 ∴ 400 = P × R × 1/100 From this we cannot get the answer and also statement II is not sufficient to answer the question.
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 = ?
