Answer:C
A and B can complete a task in eight days, whereas B and C can do the identical task in twelve days. It can be completed in 6 days if A, B, and C work together. It will be completed in the following time if A and C work together:
A. 4 days B. 6 days C. 8 days D. 12 days
Explanation: 1 day's work for (A + B + C) = 1/6; 61 day's labour for (A + B) = 1/8; 1 day's work for (B + C) = 1/12.As a result, 1 day's work for (A + C) = ( 2 x 1/6 )- ( 1/8 + 1/12 ) \s= ( 1/3 - 5/24 )= 3/24= 1/8 .As a result, A and C will complete the task in 8 days.
