A clock falls behind 10 minutes each day. How many days will it take to reach a point where the clock will indicate the correct time?

Let's analyze the situation:

The clock falls behind 10 minutes each day, which means it loses 10 minutes every day.

We want to find out how many days it will take for the clock to catch up and indicate the correct time.

To catch up by 10 minutes, the clock needs to gain 10 minutes each day instead of losing them. This is a daily change of +10 minutes.

To catch up the full 12-hour cycle (720 minutes), it will take:

720 minutes/10 minutes per day=72 days

So, it will take 72 days for the clock to indicate the correct time. The correct answer is 72.
