      Question

      A boy can swim a certain distance downstream in 2 hours

      and return in 5 hours. If the rate of stream is 3 kmph then what is the speed of boy in still water?
      A 6 kmph Correct Answer Incorrect Answer
      B 8 kmph Correct Answer Incorrect Answer
      C 7 kmph Correct Answer Incorrect Answer
      D 9 kmph Correct Answer Incorrect Answer

      Solution

      Let the speed of the boy in still water be x kmph. Then, (x + 3) × 2 = (x – 3) × 5 => 2x + 6 = 5x - 15 => 3x = 21 => x = 7 kmph
