Question
A and B together can complete a piece of work in 10
days. A alone can complete the work in 15 days. How many days will B take to complete the work alone?Solution
Let the total work be 1 unit. A’s efficiency = 1/15 (work per day). A and B together = 1/10 (work per day). B's efficiency = (1/10) - (1/15) = (3 - 2)/30 = 1/30 (work per day). Thus, B alone can complete the work in 30 days.
