  4. He attends History classes on the day following the day of his Mathematics classes.
  5. On Tuesday he attends his Sports classes.

If he attends just one subject in a day and his Sunday is free, then he is also free on

EXPLANATION

Correct Option (4)

Based on the provided statements, the schedule can be established as follows:

  • Monday: Music (Statement 1)
  • Tuesday: Sports (Statement 5)
  • Wednesday: Mathematics (Statement 2)
  • Thursday: History (Statement 4, as it follows Wednesday's Mathematics class)
  • Sunday: Free (Given)

The remaining days for classes are Friday and Saturday. The only subject yet to be scheduled is Literature. Statement 3 specifies that Literature classes are not on Friday. Therefore, Literature must be scheduled for Saturday. This leaves Friday as the only day without a scheduled class, making it a free day.

Incorrect Options:

  • Monday: George attends Music classes on Monday, as per Statement 1.
  • Thursday: George attends History classes on Thursday, as per Statement 4.
  • Saturday: George attends Literature classes on Saturday, as deduced from Statement 3 and the remaining schedule.
