If A completes work in 3 days and B completes the same work in 6 days
A's one day work = 1/3 day
B's one day work = 1/6 day
A's and B's one day work together = 1/3+1/6
= 1/2
Therefore total number of days required would be 2 if they work together
A's one day work = 1/3 day
B's one day work = 1/6 day
A's and B's one day work together = 1/3+1/6
= 1/2
