49 seconds

58 seconds

64 seconds

72 seconds

- The train's length is 230 meters, and the platform's length is 750 meters.

- For the train to completely cross the platform, it must travel a distance equal to the sum of both lengths: 230 + 750 = 980 meters.

- The train's speed is 72 km/h. To convert this to meters per second:

- 72 km/h = (72 * 1000 meters) / (60 * 60 seconds) = 20 meters/second.

- Time taken to cross the platform:

- Time = Distance / Speed = 980 meters / 20 meters/second = 49 seconds.

- Option 1: 49 seconds is correct.
