A and B together can do a work in 8 days, B and C together in 6 days, while C and A together in 10 days, if they all work together, then the work will be completed in :
A and B together can do a work in 8 days, B and C together in 6 days, while C and A together in 10 days, if they all work together, then the work will be completed in :
[A]
[B]
[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
∴ A, B and C together will finish the work in
Hence option [C] is correct answer.
