Max has to wake up for his race in the morning. He goes to bed early at 20:00 hours. What is the time he goes to sleep?

The correct option is A 8:00 p.m.
Let us convert the time to the 12-hour format.

• $\text{Hours}$ in the 12-hour format $\text{changes}$ depending upon whether the time is less than or more than 12:00 hours.
• If the number of hours is more than 12:00 hours, the time is subtracted by 12.
• The time is 20:00.
• To convert to the 12-hour format, we subtract 12 from the number of hours.
• Time in the 12-hour format = 20 - 12
  = 8
• The time is 8:00 p.m.

Hence, the correct answer is option D.
