    Question

    The distance covered by a boat while moving in

    downstream in a fixed time is 3/4 more than in upstream. The speed of stream is what % of the still water speed of boat?
    A (11.11)% Correct Answer Incorrect Answer
    B (27.27)% Correct Answer Incorrect Answer
    C (13.13)% Correct Answer Incorrect Answer
    D (17.17)% Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    As we can conclude that time is given constant, distance ∝ speed (v + u) / (v − u) = 175/100 (v) / (u) = 11/3 Required % = 3/11 x 100 = (27.27)%
