Question

Arun wakes up at 06:00 am and goes off to bed at 10:00 pm daily. These times in the 24-hour clock are ___ and ___ respectively.

• A. 18:00 hrs, 10:00 hrs
• B. 06:00 hrs, 22:00 hrs
• C. 18:00 hrs, 22:00 hrs
• D. 06:00 hrs, 10:00 hrs

Answer 1

The correct option is B 06:00 hrs, 22:00 hrs

The time upto 12:59 pm from midnight has no change while converting from 12-hour clock to 24-hour clock. But,for the time after 12:59 pm, we add 12 to the given time to convert it to 24-hour clock.

So, Badhana wakes up at 06:00 hrs (=06:00 am),
and goes off to bed at (10+12=)22:00 hrs(=10:00 pm).
