Question

the train for Mumbai every two and half hours from New Delhi railway station announcements was mad that the train for Mumbai had left 40 minutes ago and the next train will leave at 18 hours at what time was the announcement made ​

Answer 1

Explanation:

As the train moved 40 min ago, we can directly sat that. I am going to tell you with the example or may you cheat=

Suppose we have the number 3 and 2 and there is a task that 3 moved 5 minutes ago of 2 and that we have the audition how late was 2 moved, so for finding that we will see that 3 moved 5minutes ago that means the time distance is 5 minutes, that means 2 moved 5 minutes later.

Hope, it was useful because I have not read the question nicely☺️☺️
