Ratio of times taken by A and B = 1 : 3. The time difference is (3 - 1) 2 days while B take 3 days and A takes 1 day. If difference of time is 2 days, B takes 3 days. If difference of time is 60 days, B takes 3 x 60 = 90 days. 2 So, A takes 30 days to do the work. A's 1 day's work = 1 30 B's 1 day's work = 1 90 (A + B)'s 1 day's work = 1 + 1 = 4 = 2 30 90 90 45 A and B together can do the work in 45 = 22 1 days. 2 2
