--->Aptitude Problem of Yesterday 07.07.2018 (Saturday)
A can do a piece of work in 7 days of 9 hours each and B can do it in 6 days of 7 bours each. How long will they take to do it, working together 8 hours a day?
A. 2 days
B. 3 days
C. 4 days
D. 5 days
:)Solution:
-->Answer : Option B
-->Explanation :
A can complete the work in (7 x 9) = 63 hours.
B can complete the work in (6 x 7) = 42 hours.
A's 1 hour's work = (1/63) and B's 1 hour's work = (1/42)
(A + B)'s 1 hour's work = (1/63)+(1/42) = (5/126)
Both will finish the work in (126/5) hrs.
Number of days. of (8) hrs each =126/(5 x 8) = 3 days
