Problem Analysis

We have four classmates: Meruet, Kayrat, Yura, and Lena. We are given their birth dates: - One of them was born on May 7th. - Another was born on May 15th. - The third was born on August 20th. - The fourth was born on September 15th.

We also know that: - Meruet and Yura were born in different months but on the same day. - Meruet and Lena were born in the same month but on different days.

We need to determine the birth dates of each classmate.

Solution

Let's analyze the given information step by step to determine the birth dates of each classmate.

1. Meruet and Yura were born in different months but on the same day. - Since Meruet and Yura share the same birth day, we can conclude that Meruet was not born on May 15th (as Yura was born on that day). - Therefore, Meruet must have been born on May 7th.

2. Meruet and Lena were born in the same month but on different days. - Since Meruet was born on May 7th, Lena cannot be born on May 7th. - Therefore, Lena must have been born on May 15th.

3. We are left with Kayrat and Yura. - Kayrat was born on August 20th. - Yura must be the remaining classmate and was born on September 15th.

Based on the given information, the birth dates of each classmate are as follows: - Meruet: May 7th - Kayrat: August 20th - Yura: September 15th - Lena: May 15th
