Correct Answer - Option 1 : 29 hours 35 minutes
Concept used:
In the train, there is the 24-hour clock
Total number of days in May month is 31
Calculation:
Total time from 30th May 2020 at 23 ∶ 40 hours to 31st May 2020 at 00 ∶ 00 hours is 20 minutes
Total time from 31st May 2020 at 00 ∶ 00 hours to 1st June 2020 at 00 ∶ 00 hours is 24 hours
And, Total time from 1st June 2020 at 00 ∶ 00 hours to 1st June 2020 at 5 ∶ 15 hours is 5 hours and 15 minutes
Total travel time = 20 minutes + 24 hours + 5 hours + 15 minutes = 29 hours and 35 minutes
∴ The total taken by the train in the journey is 29 hours and 35 minutes
