    Question

    A2 type ‘P’ pipes can fill

    a tank in 575 hours, while B2 type ‘Q’ pipes can fill the same tank in 828 hours. (12A × 5B) type ‘P’ pipes can fill the same tank in how many hours? (Efficiency of a type P and a type Q pipe is same)
    A 7 hrs Correct Answer Incorrect Answer
    B 6 hrs Correct Answer Incorrect Answer
    C 11.5 hrs Correct Answer Incorrect Answer
    D 14 hrs Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    A2×575 = B2×828
    A2/B2 = 828/575
    A2/B2= 36/25
    A/B = 6/5
    A = 6B/5
    (12A × 5B) type 'P' pipes = 12 ×6B/5 ×5B = 72 B2
    Required time = (B2×828)/(72 ×B2) = 11.5 hrs
