Three friends converted the time of 24 hours clock in that of 12 hour clock as follows: Name of the children Time in 24 hour clock Time in 12 hour clock Cheeku 23:45 11:45 pm Bittu  16:30 04:30 am Pinki 19:28 07:28 pm Who has shown incorrect time in 12 hour clock? Correct Answer Bittu only

Given:

Time in 24 hours clock of Cheeku = 23:45

Time in 12 hours clock of Cheeku = 11:45 pm

Time in 24 hours clock of Bittu = 16:30 

Time in 12 hours clock of Bittu = 04:30 am 

Time in 24 hours clock of Pinki = 19:28  

Time in 12 hours clock of Pinki = 07:28 pm

Concept: 

To convert from a 24-hour clock to a 12-hour clock, we may have to subtract 12 to the hours after midday, e.g. 15:00 becomes 3:00 pm because 15 - 12 = 3 pm.

Calculation:

To solve this question we have to check all the given options;

⇒ Time converted by Cheeku = 23:45 - 12:00 = 11:45 pm ( correct )

⇒ Time converted by Bittu = 16:30 - 12:00 = 4:30 am ( incorrect )

⇒ Time converted by Pinki = 19:28 - 12:00 = 07:28 pm ( correct )

So the time shown by Bittu is incorrect because he has converted it as 04:30 am but it should be 04:30 pm.
