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

After 20 hours the clock will show 3*20 = 60 min = 1 hr more
Since the clock is analogue after 12 hours it will show the same time hat is 6 am and 6 pm are shown the same way.
After 20*12 = 240 hr = 10 days the clock will show 12 hr more but since 6 am and 6 pm are shown the same after 240 hr = 10 days the clock will show the correct time again.
The correct time will be shown on Monday 6 pm.

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.

The clock, which gains 3 minutes every hour, will display the correct time again at 6 PM on Tuesday, 10 days after it was set correctly at 6 PM on Saturday.
