Problem Analysis

We have four boys: Ivanov, Petrov, Sidorov, and Andreev. Each of them has a different talent: musician, ballroom dancer, choir boy, and talented artist. We are given the following information: 1. Ivanov and Sidorov were present at the conservatory, where a singer was performing. 2. Petrov and the musician posed for the artist. 3. The musician used to be friends with Andreev but now wants to be friends with Ivanov. 4. Ivanov and Sidorov are not acquainted because they are in different classes.

We need to determine who is who among the boys.

Solution

Let's analyze the given information step by step to determine the identities of the boys.

1. Ivanov and Sidorov were present at the conservatory, where a singer was performing. This means that Ivanov and Sidorov are not the musician or the artist. They must be the choir boy and the ballroom dancer, but we don't know which is which yet.

2. Petrov and the musician posed for the artist. This means that Petrov is not the musician or the artist. He must be either the choir boy or the ballroom dancer.

3. The musician used to be friends with Andreev but now wants to be friends with Ivanov. This means that the musician is not Andreev or Ivanov. Therefore, the musician must be Petrov.

4. Ivanov and Sidorov are not acquainted because they are in different classes. This means that Ivanov is not the choir boy. Therefore, Ivanov must be the ballroom dancer, and Sidorov must be the choir boy.

Based on this analysis, we can determine the identities of the boys as follows: - Ivanov is the ballroom dancer. - Petrov is the musician. - Sidorov is the choir boy. - Andreev is the talented artist.

Answer

Based on the given information, the identities of the boys are as follows: - Ivanov is the ballroom dancer. - Petrov is the musician. - Sidorov is the choir boy. - Andreev is the talented artist.
