The correct Answer is:
To determine what day the 15th of the month falls on, given that three Sundays in that month are on even-numbered dates, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Problem**: We know that there are three Sundays that fall on even-numbered dates in a month. We need to find out what day the 15th of that month is. 2. **Identifying Possible Even Sundays**: Since there are three Sundays on even-numbered dates, the possible even dates for Sundays could be 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30. 3. **Setting Up the Sundays**: For there to be three Sundays on even dates, we can assume the first Sunday falls on an even date. Let's denote the first Sunday as the 2nd of the month. The subsequent Sundays would then be: - 1st Sunday: 2nd - 2nd Sunday: 9th (2 + 7) - 3rd Sunday: 16th (9 + 7) Here, we see that the 2nd Sunday is on an even date (2), and the 3rd Sunday is also on an even date (16). However, we need to ensure that we have three Sundays on even dates. 4. **Finding Valid Even Sundays**: If we start with the 2nd as the first Sunday, the next Sundays would be: - 2nd (1st Sunday) - 9th (2nd Sunday) - 16th (3rd Sunday) - 23rd (4th Sunday) - 30th (5th Sunday) In this case, we have only one even Sunday (2nd). So, we need to try a different starting point. 5. **Trying Another Starting Point**: Let's assume the first Sunday is the 4th: - 1st Sunday: 4th - 2nd Sunday: 11th - 3rd Sunday: 18th - 4th Sunday: 25th Here, we have only one even Sunday (4th). 6. **Finding a Valid Combination**: - If we start with the 2nd Sunday on the 8th: - 1st Sunday: 8th - 2nd Sunday: 15th - 3rd Sunday: 22nd - 4th Sunday: 29th Here, we have two even Sundays (8th and 22nd), but we still need three. 7. **Final Setup**: - Let’s try starting with the 6th: - 1st Sunday: 6th - 2nd Sunday: 13th - 3rd Sunday: 20th - 4th Sunday: 27th We have two even Sundays (6th and 20th), but still not three. 8. **Conclusion**: After checking various combinations, we find that if the Sundays are on 2nd, 16th, and 30th, we have three even Sundays. The 15th will then fall on a Saturday. ### Final Answer: The 15th of that month falls on a **Saturday**.
