Problem Analysis

We are given a scenario where eight students were called to the principal's office because one of them broke a window in the classroom. Each student provides a statement about who broke the window. We need to determine who broke the window based on the information provided.

Solution

To solve this problem, we need to analyze each student's statement and determine which statements are true. We can then count the number of true statements to identify the student who broke the window.

Let's analyze each student's statement:

1. Egor: "Andrey broke it!" 2. Svetlana: "Vika broke it." 3. Olya: "Svetlana broke it." 4. Misha: "It was someone from outside!" 5. Nadya: "Yes, Olya is right..." 6. Kolya: "It was either Vika or Svetlana!" 7. Andrey: "Neither Vika nor Svetlana did it." 8. Vika: "Andrey didn't do it."

Based on the given statements, we can make the following observations:

- If Egor's statement is true, then Andrey broke the window. - If Svetlana's statement is true, then Vika broke the window. - If Olya's statement is true, then Svetlana broke the window. - If Misha's statement is true, then someone from outside broke the window. - If Nadya's statement is true, then Olya's statement is true. - If Kolya's statement is true, then either Vika or Svetlana broke the window. - If Andrey's statement is true, then neither Vika nor Svetlana broke the window. - If Vika's statement is true, then Andrey didn't break the window.

We need to find three true statements among these eight statements. Let's analyze each statement:

- If Egor's statement is true, then Andrey broke the window. (Statement 1) - If Svetlana's statement is true, then Vika broke the window. (Statement 2) - If Olya's statement is true, then Svetlana broke the window. (Statement 3) - If Misha's statement is true, then someone from outside broke the window. - If Nadya's statement is true, then Olya's statement is true. (Statement 3) - If Kolya's statement is true, then either Vika or Svetlana broke the window. (Statement 2 or 3) - If Andrey's statement is true, then neither Vika nor Svetlana broke the window. - If Vika's statement is true, then Andrey didn't break the window.

From the above analysis, we can see that the true statements are:

1. Egor: "Andrey broke it!" 2. Svetlana: "Vika broke it." 3. Olya: "Svetlana broke it."

Therefore, based on the information provided, we can conclude that Andrey, Vika, and Svetlana are the three students who broke the window.

Answer

Based on the given statements, the three students who broke the window are Andrey, Vika, and Svetlana.
