Man A completes the work in 15 days so he can do 1/15th of the work in 1 day.
Man B completes the work in 20 days so he can do 1/20th of the work in 1 day.
If they work together to complete the job then both A and B will complete the piece of work in:
= 1/15 + 1/20
= 15+20/20*15
= 20 + 15/300
= 35/300
= 7/60
Thus, both A and B will do the same work in 60/7 days or 8 full day and 4/7 days part of a day
