An analogue clock is gaining three minutes every hour. If you set it to the correct time at 6pm on Saturday, when will it show the correct time again.

It must gather 12 hours or 12*60=720 minutes. Every hour it gathers 3 minutes, so it needs 240 hours or exactly 10 days. 10 days from Saturday is Tuesday, at 6 PM.
