Answer:
Work done by A in 1 day=1/15
Word done by B in 1 day = 1/10
If both work together for one day=1/15+1/10=2+3/30=5/30=1/6
If they complete 1/6 of the work in one day they will complete total work in 6 DAYS.

Ans-6 days
Since A does the job in 15 days
1/15
And B does the job in 10 days
1/10
If they work together they will finish the job in
1/15+1/10 =1/6
Which is equal to 6 days
