Problem Analysis

A Baba Yaga entered a room with a round table surrounded by 60 chairs. Some of the chairs were occupied by guests. Baba Yaga cannot sit in a chair if someone is sitting next to her. We need to determine the minimum number of guests that could be sitting at the table at that moment.

Solution

To find the minimum number of guests that could be sitting at the table, we need to consider the seating arrangement that satisfies the condition that no one is sitting next to Baba Yaga.

Let's analyze the possible seating arrangements:

1. If Baba Yaga sits in a chair, there will be two chairs next to her that cannot be occupied by guests. This means that a maximum of 57 guests can be sitting at the table. 2. If Baba Yaga sits in a chair and leaves one chair empty next to her, there will be one chair on each side of the empty chair that cannot be occupied by guests. This means that a maximum of 56 guests can be sitting at the table. 3. If Baba Yaga sits in a chair and leaves two chairs empty next to her, there will be two chairs on each side of the empty chairs that cannot be occupied by guests. This means that a maximum of 55 guests can be sitting at the table.

Therefore, the minimum number of guests that could be sitting at the table is 55.

Note: This solution assumes that Baba Yaga cannot sit in a chair that is already occupied by a guest.
