    Question

    A can copy 75 pages in 25 hours, A and B together can

    copy 130 pages in 26 hours. Then in how many hours B can copy 30 pages.
    A 54 hours Correct Answer Incorrect Answer
    B 60 hours Correct Answer Incorrect Answer
    C 52 hours Correct Answer Incorrect Answer
    D 56 hours Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Number of pages copied by x in hour = 75/25 = 3
    Number of pages copied by x and y in 1 hour = 130/26 = 5
    ∴ Number of pages copied by y in 1 hour = 5 – 3 = 2
    ∴ Required time = 2 x 30 = 60 hours
