A Completes 1/10 th of the work in one day
B completes 1/15th of the work in one day
Together A and B complete 1/10 + 1/15 = 10/60 th work in one day
Thus it take 60/10 = 6 days to complete the work by A and B together.
B completes 1/15th of the work in one day

In one day A does 1/10th of the work while B does 1/15th of the work. Therefore in one day A and B together does (1/10+1/15)th of the work which is equal to 5/30= 1/6th of the work.
Therefore they will do the full work in 6 days.
Therefore they will do the full work in 6 days.
