- First, let's find the speed of the train.

- The train’s length is 270 m, and it crosses a pole in 24 seconds.

- Speed = Distance / Time = 270 / 24 = 11.25 m/s.

- The train takes 1 minute (60 seconds) to cross the tunnel.

- In 60 seconds, distance covered = Speed × Time = 11.25 × 60 = 675 m.

- While crossing the tunnel, the train covers its own length plus the length of the tunnel.

- So, 270 (train) + tunnel length = 675

- Thus, Tunnel length = 675 - 270 = 405 m.

- Option 2, 405, is correct!
