Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Work backwards from the next train's time to find the previous train's time, then add the elapsed time.
Step 2: Detailed Explanation:
1. Next train = 18:00 hrs. 2. Interval = 2 hours 30 minutes. 3. Previous train time = 18:00 - 2:30 = 15:30 hrs.
Step 3: Calculation:
The announcement said the train left 40 minutes ago. Announcement time = Previous train time + 40 minutes Announcement time = 15:30 + 0:40 = 16:10 hrs.
Step 4: Final Answer:
The announcement was made at 16:10 hrs. Thus, the correct option is (e).
