To complete a work, a person A takes 10 days and another person B takes 15 days. If they work together, in how much time will they complete the work?
A’s one day work (efficiency) = 1/10
B’s one day work (efficiency) = 1/15
Total work done in one day = 1/10 + 1/15 = 1/6
Therefore, working together, they can complete the total work in 6 days.
