Answer 2

Problem Analysis

We are given that a boy said, "The difference between the number of months I have lived and the number of years I have lived today is equal to 111." We need to determine the boy's date of birth based on this information.

Solution

Let's assume the boy's date of birth is on February 16th. We can calculate the difference between the number of months and the number of years from February 16, 2016, to the current date. If the difference is indeed 111, then our assumption is correct.

To calculate the difference, we need to consider leap years. Leap years occur every four years, except for years that are divisible by 100 but not divisible by 400. We will take this into account when calculating the number of days.

Calculation

1. Calculate the number of days from February 16, 2016, to the current date (Wednesday, December 13, 2023). - February 16, 2016, to February 16, 2023: 7 years * 365 days = 2,555 days - February 16, 2023, to December 13, 2023: 9 months * 30 days = 270 days - Total: 2,555 days + 270 days = 2,825 days

2. Calculate the number of leap years between 2016 and 2023. - Leap years: 2016, 2020, 2024 (not included), 2028 (not included), 2032 (not included), 2036 (not included), 2040 (not included), 2044 (not included) - Total: 1 leap year

3. Adjust the total number of days by subtracting the number of leap years. - Total: 2,825 days - 1 day = 2,824 days

4. Calculate the number of months and years based on the adjusted total number of days. - Number of months: 2,824 days / 30 days = 94 months - Number of years: 94 months / 12 months = 7 years and 10 months

Conclusion

Based on the calculation, if the boy's statement is true, then he was born on April 16, 2015.
