Question
Two numbers are in the ratio 2:7. The product of their
H.C.F. and L.C.M. is 5054. The sum of the numbers is:Solution
Let the numbers be 2x and 7x respectively. First number × second number = HCF × LCM => 2x × 7x = 5054 => x2 = [5054/(2×7)] = 361 => x = √361 = 19 Sum of the numbers = 2x + 7x = 9x = 9 × 19 = 171
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
