A can do a piece of work in 10 days, and B can do the same work in 15 days. In how many days can they complete the work if they work together?
Answer:
6 days
A's 1 day's work = 1/10. B's 1 day's work = 1/15. Together, their 1 day's work = (1/10) + (1/15) = (3+2)/30 = 5/30 = 1/6. Therefore, working together, they will complete the work in 6 days.
