  2. 3.5

  3. 4

  4. 4.5


Correct Option: C

AI Explanation

To solve this question, we need to consider the relative motion of the train and the man on the platform.

Given: Length of the train = 300m Time taken by the train to cross the man = 10 seconds

Let's first find the speed of the train. We know that speed = distance / time.

Speed of the train = 300m / 10s = 30 m/s

Now, we need to find the time taken by the train to cross a platform of length 120m.

When the train is crossing the platform, it covers the distance equal to its own length (300m) plus the length of the platform (120m).

Total distance = 300m + 120m = 420m

The time taken can be found using the formula: time = distance / speed.

Time taken = 420m / 30 m/s = 14 seconds

Therefore, the time taken by the train to cross the platform of length 120m is 14 seconds.

Comparing this with the options given: A) 3 seconds - incorrect B) 3.5 seconds - incorrect C) 4 seconds - correct D) 4.5 seconds - incorrect

So, the correct answer is C) 4 seconds.
