Find the length of the platform.
A. A train X, which is running at the speed of 25 $\frac{km}{hr}$, takes 18 seconds to pass a platform.
B. The train X crosses a man who is walking at 5 $\frac{km}{hr}$ in the opposite direction in 12 seconds.
C. The train X crosses a stationary pole in 14.4 seconds.

• A. Any two of them
• B. Either B or C
• C. Any of them
• D. Only C

Answer 1

Answer: (A)

Any two of them

Answer 2

By Using Condition C alone, we can find the length of the train. Combining the A and C will allow us to calculate the platform length (since we can subtract the train's length from the total distance the train covers in 18 seconds). So, Any two of these conditions would be enough to solve the problem.

The correct option is (A): Any two of them
