    A man can row 8 km/hr in still water. If the speed of

    the current is 4 km/hr, it takes 5 hours more in upstream than in the downstream for the same distance. The distance is
    A 72 km Correct Answer Incorrect Answer
    B 150 km Correct Answer Incorrect Answer
    C 30 km Correct Answer Incorrect Answer
    D 40 km Correct Answer Incorrect Answer
    E 105 km Correct Answer Incorrect Answer

    Solution

    Let the required distance be x km. Therefore, x/(8 – 4) – x/(8 + 4) = 5 ⇒ x/4 – x/12 = 5 ⇒ (3x – x)/12 = 5 ⇒ x = 5 x 12/2 = 30 km
