Show answer & explanation
Correct answer: A
To completely cross the platform, the train must cover a total distance equal to its own length plus the platform's length. Total distance = 200 m + 1000 m = 1200 m. Time taken = Total distance / Speed = 1200 m / 20 m/s = 60 seconds. Therefore, the time taken is 1 minute.
