Answer 2

Answer:

8/3 days.

Step-by-step explanation:

A and B can do in 1 day= 1/3

B and C can do in 1 day= 1/4

A and C can do in 1day= 1/6

A+B + B+C + A+C= 1/3 + 1/4 + 1/6

2( A+ B + C). = 9/12

A+B+C. = 3/8

Total time taken by A, B and C to finish work=.

x days. = 1work

days. = 1/x work

1days. = 1/x

3/8. = 1/x

x. = 8/3 days.
