The ratio of the speeds of a train and a man 6 : 1 . The length of the train is 650 m and crosses a pole in 1 minute 5 seconds. In how much time will the man cross the 240 m long platform?

  • A. 1 min 24 sec
  • B. 1 min 24 sec
  • C. 1 min 24 sec
  • D. 1 min 24 sec

Answer: Option A

Explanation:

Speed of the train = 650/65 = 10 mps.
Speed of the man = 10/6 = 5/3 mps.
Time for the man to cross the platform = 240/(5/3) = 144 seconds = 2 minutes 24 seconds. Ans: D
