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
( A can work in 6 days)
therefore , A can do 5/12 work in= 6×5/12
= 5/2 days
2 1/2 days.
