E Correct answer
Explanation

When the train crosses a pole in 15 seconds, it covers its own length L. When it crosses a 150m platform in 25 seconds, it covers L+150. The extra 10 seconds are for the 150m platform, so speed = 150÷10 = 15 m/s. Converting to km/h: 15 × 3.6 = 54 km/h. Options A (40), B (36), C (50), and D (45) are all incorrect conversions.
