Step-by-step explanation:

Consider the provided information.

A and B can do a given piece of work in 8 days.

The one day work of A and B is = 1/8

B and C can do the same work in 12 days

The one day work of B and C is = 1/12

Let A and C complete the work in x days

The one day work of A and C is =1/x

A, B and C can do a given piece of work in 6 days.

The one day work of A, B and C is = 1/6

Thus, (A+B+B+C+C+A)’s one day’s work =1/8+1/12+1/x

2(A+B+B+C+C+A)=3x+2x+24x/24

2*1/6=5x+24/24x

8x=5x+24

3x=24

x=8

Hence, A and C together complete the work in 8 day.
