Examine the following statements: 1. George attends Music classes on Monday. 2. He attends Mathematics classes on Wednesday. 3. His Literature classes are not on Friday. 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

To solve this elegantly, let's just make a simple list of the days and fill in what we know for sure. There are 5 subjects and 6 available days (Mon-Sat, since Sunday is free).\n\n1. **Monday**: Explicitly given as **Music**.\n2. **Tuesday**: Explicitly given as **Sports**.\n3. **Wednesday**: Explicitly given as **Mathematics**.\n4. **Thursday**: The rule says History is the day after Math. Since Math is Wednesday, **History** falls on Thursday.\n\nNow we are left with two days: **Friday** and **Saturday**.\nWe have one subject left: **Literature**.\n\nThe rule says Literature is **not** on Friday. Therefore, Literature must go to **Saturday**.\n\nThis leaves **Friday** as the only day with no subject assigned. Thus, Friday is the free day.
