      Question

      A man can row 16 km/hr in still water. It takes him

      thrice as long to row up as to row down the river. Find the speed of the man against the current.
      A 8 km/hr Correct Answer Incorrect Answer
      B 10 km/hr Correct Answer Incorrect Answer
      C 12 km/hr Correct Answer Incorrect Answer
      D 14 km/hr Correct Answer Incorrect Answer
      E 6 km/hr Correct Answer Incorrect Answer

      Solution

      Let man’s rate upstream be x kmph. Then his rate downstream = 3x  kmph. Rate in still water =    kmph  = 2x  kmph 16  = 2x x  = = 8, So, Rate upstream = 8 kmph.
