Given Information:
- Speed of the train = 54 km/hr
- Time taken to pass the platform = 36 seconds
- Time taken to pass a man standing on the platform = 20 seconds
Calculating the Length of the Train:
- The time taken by the train to pass the man and the platform is different due to the length of the train.
- Let L be the length of the train in meters.
- When the train passes the platform, it covers a distance equal to its own length plus the length of the platform.
- When the train passes the man, it covers a distance equal to its own length.
Calculating Speed:
- Speed = Distance/Time
- 54 km/hr = (L + length of platform)/36
- 54*1000/3600 = (L + length of platform)/36
- 15 = (L + length of platform)/36
- L + length of platform = 15*36
- L + length of platform = 540
Calculating Length of Platform:
- Speed = Distance/Time
- 54 km/hr = L/20
- 54*1000/3600 = L/20
- 15 = L/20
- L = 15*20
- L = 300
Calculating the Length of the Platform:
- L + length of platform = 540
- 300 + length of platform = 540
- Length of platform = 540 - 300
- Length of platform = 240 meters
Therefore, the length of the platform is 240 meters. Hence, option C is correct.
- Speed of the train = 54 km/hr
- Time taken to pass the platform = 36 seconds
- Time taken to pass a man standing on the platform = 20 seconds

Calculating Length of Platform:
- Speed = Distance/Time
- 54 km/hr = L/20
- 54*1000/3600 = L/20
- 15 = L/20
- L = 15*20
- L = 300
Calculating the Length of the Platform:
- L + length of platform = 540
- 300 + length of platform = 540
- Length of platform = 540 - 300
- Length of platform = 240 meters
Therefore, the length of the platform is 240 meters. Hence, option C is correct.
