Question
Given below is a number series. One term of the series
is denoted by X. You have to calculate the value of X and by using the value, you have to replace the question mark (?): If 7 5 20 52.5 160.5 Then, (X + 1) ( X – 1) = ?Solution
7 `xx` 0.5 + 0.5 = 4 4`xx` 1 + 1 = 5 5 `xx` 1.5 + 1.5 = 9 9 `xx` 2 + 2 = 20 20`xx` 2.5 + 2.5 = 52.5 52.5 `xx` 3 + 3 = 160.5 x = 9 (9-1) (9+1) =`10xx8` = 80
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
What approximate value will replace the question mark (?) in the following?
? =...
? = 49.97% of 38.09% of 1998.95
- 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.)
