Length of the platform = speed of train * extra time taken to cross the platform.
Length of platform = 72 kmph * 12 seconds.
.'. 72 kmph = 5/18 x 72 = 20 m/sec.
Therefore, length of the platform = 20 m/s * 12 sec = 240 meters.
Length of platform = 72 kmph * 12 seconds.

Understanding the problem:
The train takes 30 seconds to cross the platform and 18 seconds to cross a man standing on the platform. We need to find the length of the platform.
Approach to solving the problem:
- Let the length of the platform be 'x' meters.
- The speed of the train is given as 72 kmph, which is equivalent to 20 m/s.
Calculating the length of the platform:
- When the train crosses the platform, it travels the length of the train plus the length of the platform.
- The time taken to cross the platform is 30 seconds, so the distance covered is 20*30 = 600 meters.
- When the train crosses the man, it travels only the length of the train.
- The time taken to cross the man is 18 seconds, so the distance covered is 20*18 = 360 meters.
- The difference between the two distances gives us the length of the platform: 600 - 360 = 240 meters.
Therefore, the length of the platform is 240 meters, which corresponds to option 'A'.
