      Question

      If a man rows at the rate of 25 kmph in still

      water and his rate against the current is 5.5 kmph, then the manrsquo;s rate along the current is:
      A 44.5 kmph Correct Answer Incorrect Answer
      B 35.5 kmph Correct Answer Incorrect Answer
      C 38.5 kmph Correct Answer Incorrect Answer
      D 36 kmph Correct Answer Incorrect Answer

      Solution

      Let manrsquo;s speed downstream be x kmph. Manrsquo;s rate in still water = (x + 5.5)times; frac12; kmph 25 = (x + 5.5)times; frac12; kmph 50 = (x + 5.5) kmph x = 50 ndash; 5.5 = 44.5 kmph
