Correct Answer: Option A

Explanation:
Speed of first train = 100 / 10 = 10 m/s. Speed of second train = 100 / 20 = 5 m/s. Total distance to cross = 100 + 100 = 200 meters. Relative speed in opposite directions = 10 + 5 = 15 m/s. Time taken = 200 / 15 = 13.33 seconds.

Correct Answer: Option D

Explanation:
By 8:00 AM, Train A has run for 2 hours, covering 40 * 2 = 80 km. Remaining separation distance = 320 - 80 = 240 km. Relative speed = 40 + 60 = 100 km/h. Time after 8:00 AM = 240 / 100 = 2.4 hours = 2 hours 24 minutes. Meeting time = 8:00 AM + 2 hours 24 minutes = 10:24 AM.
