Question
A man invested a certain amount of sum at 12.5% per
annum simple interest and earned an interest of Rs.2400 after 4 years. If the same amount is invested at 20% per annum compound interest, compounded annually for two years, then find the interest.Solution
Let the certain sum of money be Rs.P. So,  P x 0.125 x 4 = 2400 => P = Rs.4800 Desired interest = [(1.2)2 – 1] x 4800 = Rs.2112
1219.98 ÷ 30.48 × 15.12 = ? × 2.16
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.)...
`1804/898-:99/699xx749/751=?`
(√845 ×19.932+ √4230 ×14.385)/(√1765 ×4.877 ) = ?
Direction: Please solve the following expression and choose the closest option
`(13.022)^(2)+ (42.93)^(2)-(53.125)^(2)+(192.33xx14.88)=?- (88.44)^(2)- (42.03 xx 23.12)`
√49 + 6.66% of 1725 + 22² = ?² - √361Â
