      Question

      Ratio of speeds of ‘A’ and ‘B’ is 6:7,

      respectively. If they participate in a 140-metre race and ‘B’ gives ‘A’, a head start of ‘m’ metres, then they finish the race at the same time. Find the value of ‘m’.
      A 21 metres Correct Answer Incorrect Answer
      B 15 metres Correct Answer Incorrect Answer
      C 20 metres Correct Answer Incorrect Answer
      D 18 metres Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the distance covered by ‘A’ in the time ‘B’ covers 140 metres be ‘x’ metres (x/140) = (6/7) Or, x = 120 So, m = 140 – 120 = 20 metres
