    A man can row at 4 kmph in still water. If the velocity

    of current is 3 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
    A 5 km Correct Answer Incorrect Answer
    B 7 km Correct Answer Incorrect Answer
    C 8 km Correct Answer Incorrect Answer
    D 12 km Correct Answer Incorrect Answer
    E 3 km Correct Answer Incorrect Answer

    Solution

    Let the distance be x km. Speed upstream = 4 – 3 = 1 kmph Speed downstream = 4 + 3 = 7 kmph => (x/7) + (x/1) = 8 => (x + 7x)/7 = 8 => 8x = 56 => x = 7 km
