Answer:

Answer is 5/2 days

Step-by-step explanation:

A can do job in= 6 days therefore, work done by A in 1 day = 1/6

B can do a job in = 8 days

therefore, work done by B in 1 day = 1/8

work done by both (A+B) in 1 day = 1/6+1/8

= 4+3/24 = 7/24

work done by both A and B in 2 days = 7/24*2

= 7/12

So remaining work = 1-7/12

= 12-7/12 = 5/12

V

(A can work in 6 days)

therefore, A can do 5/12 work in= 6×5/12

= 5/2 days

2 1/2 days.
