Scrap 17

Answer: 

There are two reasons:

• First, Ajay is double counting a lot of the days. A lot of the time spent sleeping, eating, and relaxing occurs during weekends and the summer. Weekends also occur during the summer, so all of these hours are getting counted several times.

• Secondly, school isn't an all-day thing. So the 4 days actually represents more days of school. If school is 6 hours per day, those four days represents 16 days of school.
