Problem Analysis

We have four girls named Masha, Valya, Tanya, and Galya living in a room. Two of them are the same age. We know that Tanya is older than Masha, who is younger than Galya. Valya is younger than Galya but older than Tanya. We need to determine which two girls are the same age.

Solution

To solve this problem, let's analyze the given information step by step:

1. Two of the girls are the same age. 2. Tanya is older than Masha. 3. Masha is younger than Galya. 4. Valya is younger than Galya. 5. Valya is older than Tanya.

From the given information, we can deduce the following relationships:

- Tanya > Masha - Masha < Galya - Valya < Galya - Valya > Tanya

Let's analyze these relationships further:

1. Tanya is older than Masha, and Valya is older than Tanya. Therefore, Valya must be older than Masha. 2. Masha is younger than Galya, and Valya is younger than Galya. Therefore, Valya must be younger than Galya, and Masha must be younger than both Galya and Valya.

Based on these deductions, we can conclude that Valya and Tanya are the same age.

Answer

The two girls who are the same age are Valya and Tanya.
