- The speed of the train is calculated by dividing its length by the time it takes to cross the pole.

- Speed = 240 m / 16 s = 15 m/s.

- When crossing the platform, the train covers its own length plus the platform’s length.

- Total time taken to cross the platform is 42 seconds.

- Total distance covered = speed × time = 15 m/s × 42 s = 630 m.

- The additional length (platform) is obtained by subtracting the train’s length from the total distance.

- Platform length = 630 m - 240 m = 390 m.

- The correct option is Option 4: 390 m.
