Your friend gave you a clock for your birthday, but unfortunately, it's very unreliable. This one gains exactly 12 minutes every hour.

It is now showing 10pm and you know that it was correct at midnight, when you set it.

If the clock stopped four hours ago, what is the correct time now?

Clock worked from midnight to 10 PM, it gives 22 hours.
4 hours ago the correct time was 22:00 - 22*12 mins= 17:36 hrs
Now time is 17:36+4=21:36 hrs
