Question
A and B together can complete a work in 12 days. B alone
can complete the same work in 30 days. In how many days will A alone complete the work?Solution
Let the total work be 1 unit. A + B’s 1-day work = 1/12, and B’s 1-day work = 1/30. A’s 1-day work = 1/12 - 1/30 = 3/60 = 1/20. So, A alone will complete the work in 20 days. Answer: d) 20 days.
