The following steps are involved in finding the total time taken by both A and B together to complete a work, when A takes 4 days and B takes 12 days to complete the work individually. Arrange them in sequential order.
(A) A and B's 1 day work = `(1)/(4) + (1)/(12) = (4)/(12) = (1)/(3).`
(B) `therefore ` Both A and B together can complete the entire work in 3 days.
(C) A's 1 day work = `(1)/(4)`. B's 1 day work = `(1)/(12)`.
