Question
Each question below is followed by two statements I and
II. You have to decide whether the data given in the statements are sufficient to answer the question. In how many days can A and B together complete a piece of work?
I. A alone can complete the work in 12 days and B alone can complete it in 18 days.
II. A and B together can complete 5/36 of the work in one day.
Solution
ATQ, From I: Aโs 1-day work = 1/12 Bโs 1-day work = 1/18 Together in 1 day = 1/12 + 1/18 = (3 + 2) / 36 = 5/36 So total time = 1 รท (5/36) = 36/5 days. I alone is sufficient. From II: Given directly: in 1 day they do 5/36 of the work. Total time = 1 รท (5/36) = 36/5 days. II alone is also sufficient. Either I alone or II alone gives the answer.
