Explanation

Statement I gives distance (200 km) and speed (40 km/h), so time taken = 200/40 = 5 hours. Departing at 8 pm, the train reaches at 1 am. Statement I is sufficient alone.

AI explanation

Statement I provides both the distance of 200 km and the speed of 40 km/h, so by applying the formula Time = Distance / Speed, the travel time is 200 / 40 = 5 hours. Adding this 5-hour travel duration to the 8 pm departure time gives a precise arrival time of 1 am. Statement II only provides a broad time window and cannot give an exact arrival time, making the data in statement I alone sufficient to answer the question.
