Answer:
2 days.
Step-by-step explanation:
Work done by first man in 3 days = 1
Work done by that man in 1 day= 1/3
Work done by second man in 6 days = 1
Work done by second man in 1 day= 1/6
Work done by them together in 1 day = 1/3+1/6
= 3/6 = 1/2
So,1/2 work done by them together in 1 day
So, whole work done by them together in days = 2 days
Hence it will take 2 days if they do work together.
