3.5 On the first day of the sports competition, $\frac{1}{6}$ of the boys' team and $\frac{1}{7}$ of the girls' team did not meet the qualifying standards and were eliminated from further competition. Over the remaining period of the competition, an equal number of athletes from both teams were eliminated due to non-compliance with the standards. In total, by the end of the trials, 48 people from the boys' team and 50 people from the girls' team did not meet the qualifying standards, but among the total number of athletes who met the qualifying standards, there were twice as many girls as boys. What was the initial number of athletes in each team?

## Relationships "more - less"
3.5 Let $x$ be the number of boys who met the credit standards and $2x$ be the number of girls. Thus, the initial number of team members consists of $x+48$ boys and $2x+50$ girls. By the end of the first day of the competition, $\frac{1}{6}(x+48)$ boys and $\frac{1}{7}(2x+50)$ girls dropped out. Later, an equal number of athletes dropped out from both teams, so

$48-\frac{1}{6}(x+48)=50-\frac{1}{7}(2x+50)$,

from which $x=24$. Therefore, the initial number of team members is 72 boys and 98 girls.

Answer: 72 boys and 98 girls.
