      Question

      A train crosses a pole and a platform of length 300

      metres in 5 seconds and 20 seconds, respectively. Find the length of train.
      A 60 metres Correct Answer Incorrect Answer
      B 80 metres Correct Answer Incorrect Answer
      C 100 metres Correct Answer Incorrect Answer
      D 120 metres Correct Answer Incorrect Answer

      Solution

      Let the speed of train be 'v' m/s.
      Length of train = '5v' metres

      So, (5v + 300) ├╖ 20 = 'v'

      Or, 5v + 300 = 20v
      Or, 15v = 300
      So, 'v' = 20

      Therefore, length of the train = 5 ├Ч 20 = 100 metres
