Question
The efficiency of A, B, C, D are in the ratio of 6 : 5 :
4 : 3. If A and C can do a work together in 6 days. Then How much days B and D will take to complete the same work?Solution
Efficiency of (A+C) = (6+4) = 10 Days taken by (A+C) together to complete the work = 6 days Efficiency of (B+D) = (5+3) = 8 So, B and D will take time = (Total days of (A+C)×Total Efficiency of (A+C))/(Total Efficiency of (B+D)) = (6 ×10)/8 = 60/8 = 7(1/2) days
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
