Answer:
6
Step-by-step explanation:
'A' complete 1/12 parts of the job in a day
'B' complete 1/36 parts of the job in a day
'A' worked 4 days
1/12×4=1/3 part
Remaining part of the work
1-1/3=2/3 part
Then 'B' joint 'A'
1/12+1/36=4/36=1/9
> 'A' and 'B' work together1/9part in a day
> 'A' and 'B' work together 1 part in 9 day
> 'A' and 'B' work together2/3part in 9×2/3=6
