Question
Quantity I. A sum of money becomes tripple in 4 years at
compound interest, compounded annually. In how many years it will become 9 times? Quantity II. What must be the rate of interest if a given amount tripled itself in 20 years? Study the following information carefully and answer the Questions given below:Solution
Quantity II. Since the amount was Rs 100. It becomes Rs 300 in 20 years. Rs 300 – Rs 100 = Rs 200 interest In 20 years, interest is Rs 200 In 1 year, the interest is Rs 200/20 Rate of interest = 10% per annum Hence Quantity I < Quantity II
85.22 of 499.98% + 299.99 ÷ 30.18 = ?
783 ÷ 42.59 × 25.86 =?
118.95 – 24.10 + (91.90 ÷ 22.89 × 12.14) = ?
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.)<...
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
? = 16.08 + 13.99 × 25.07
(23.99)2 – (17.99)2 + (1378.88 + 44.88) ÷ ? = 607.998
25.31% of 5199.90 + (19.9 × 17.11) + 46.021 =? + 168.98
