A does work in 10 days
B does work in 15 days
A s part of work done in a day 1/10
B s part of work done in a day 1/15
A work in 5 days work done = 5/10 =1/2
remaining work =1-1/2=1/2
work done by A+B in a day
= 1/10 + 1/15 = 5/30 =1/6
A+B takes 6 days to finish the work
A+B takes 6/2 =3 days to finish 1/2 work
total no of days they worked together =3
