Problem Analysis

We are given that three girls, Masha, Lena, and Nadya, received different grades in school: one received a 3, one received a 4, and the other received a 5. We are also given three additional pieces of information: 1. The girl who was first from the right received a 3. 2. The girl to the left of Lena received a 4. 3. The girl to the right of Nadya received a 5.

We need to determine which girl received which grade.

Solution

Let's analyze the given information step by step to find the solution.

1. The girl who was first from the right received a 3. - This means that Masha received a 3, as she is the girl who was first from the right.

2. The girl to the left of Lena received a 4. - Since Masha received a 3, Lena cannot receive a 4. - Therefore, Nadya must have received a 4.

3. The girl to the right of Nadya received a 5. - Since Nadya received a 4, Lena cannot receive a 5. - Therefore, Lena must have received a 3.

Based on the above deductions, we can conclude that: - Masha received a 3. - Lena received a 4. - Nadya received a 5.

Therefore, Masha received a 3, Lena received a 4, and Nadya received a 5.

Answer

Masha received a 3, Lena received a 4, and Nadya received a 5.
