A and B can do a piece of work in 18 days, B and C in 24 days, A and C in 36 days. Working together they can do the work in?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 16
LCM of (10, 24, 36)
LCM = 72 = total work unit
(A + B) + (B + C) + (A + C) = 4 + 3 + 2
2(A + B + C) = 9
A + B + C = 9/2 units/day
Working together, they can complete the work in = 72/(9/2) = 16 days
