    Question

    A can walk a certain distance in 11 days when he rests 8

    hours a day. How long will he take to walk twice the distance, twice as fast and resting twice as long each day?
    A 4(1/2) days Correct Answer Incorrect Answer
    B 11 days Correct Answer Incorrect Answer
    C 15(1/2) days Correct Answer Incorrect Answer
    D 22 days Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Working hours per day = 24 – 8 = 16 hours Total working hours = 16 ×11 = 176 hours Distance is doubled and speed too. (Both cancel each other) New working hours (per day) = 24 – 16 = 8 hours ∴ Required Time = 176/8 = 22 days
