The number of gold medals won by the students of city B at this district Spartakiade is $g$, the number of silver medals is $s$, and the number of bronze medals is $b$. According to the problem:

$$
g+s+b=42 \quad(1) ; \quad s=\frac{63}{3}=21 \quad(2) ; \quad 10<b<12
$$

From this, since $b$ is an integer, $b=11$ and thus, due to (1) and (2), $g=42-21-11=10$. The students of city B won 10 gold, 21 silver, and 11 bronze medals.
## Task 1 - 140821

At a circular Spartakiade, a total of 61 gold medals, 63 silver medals, and 60 bronze medals were awarded to the participants.
