Q. A clock, which loses uniformly, is 15 min fast at 9 am on 3rd of the December and is 25 min less than the correct time at 3 pm on 6th of the same month. At what time it was correct?
✅ Correct Answer: (C)
2 : 15 pm on 3rd
Explanation: Time of the last train leaving the station = (18 : 00 - 2 : 30)h = 15 : 30h
But this happens 40 min before the announcement is made.
Hence, Time of making announcement = (15 : 30 + 0 : 40) = 16 : 10h
But this happens 40 min before the announcement is made.
Hence, Time of making announcement = (15 : 30 + 0 : 40) = 16 : 10h
