Shapovalov A.V.

Children from two classes came to the circle: Vanya, Dima, Egor, Inna, Lesha, Sasha, and Tanya. When asked: "How many of your classmates are here?" each one honestly answered "Two" or "Three". But the boys thought they were only being asked about boy classmates, while the girls correctly understood that they were being asked about everyone. Is Sasha a boy or a girl?
The gender of each child, except for Sasha, is determined unambiguously by their names, so there are either 4 or 5 boys at the club.

Suppose some boys are in different classes. Then their answers show that at least three boys from each class came to the club. This is a contradiction. Therefore, all the boys present are classmates, but then there could not have been five of them. This means Sasha is a girl.

## Answer

A girl.
