A and B can do a piece of work in 8 days, B and C can do the same work in 12 days and A and C complete it in 8 days. In how many days A, B and C can complete the whole work, working together?
Answer & explanation
Correct answer: option 2
The above chart was obtained after following the details of the question:
Efficiency of A+B = 3
Efficiency of B+C = 2
Efficiency of A+C = 3
Efficiency of 2(A + B + C) = 8
Efficiency of A + B + C = 4
Days required by A, B and C together to complete the work = \(\frac{24 }{ 4}\) = 6 days
