A and B together can do a work in 10 days. B and C together can do the work in 6 days. A and C together can do the work in 12 days. Then A, B and C together can do the work in :
A and B together can do a work in 10 days. B and C together can do the work in 6 days. A and C together can do the work in 12 days. Then A, B and C together can do the work in :
[A]14 days
[B]28 days
[C]
[D]
(A + B)’s 1 day’s work
(B + C)’s 1 day’s work
(C + A)’s 1 day’s work
On adding all above equations,
2 (A + B + C)’s 1 day’s work
∴ (A + B + C)’s 1 day’s work
∴ All three together will complete the work in
Hence option [C] is correct answer.
