10. Vера and Аnya attend a math club, in which there are more than $91 \%$ boys. Find the smallest possible number of club participants.
10. Let $x$ be the number of participants in the club, and $y$ be the number of girls. Then, according to the conditions of the problem, $0.09 x > y$ or $9 x > 100 y$, where $x$ and $y$ are natural numbers. Solving the problem by enumeration, we will verify that the smallest possible solution for $y=2$ is achieved at $x=23$. Therefore, there are no fewer than 23 people in the club.
