## Task 2 - 330512

At a birthday party, a game is played with blue game tokens and an equal number of red game tokens.

After some time, each child had received 12 blue and 15 red game tokens, and there were still 48 blue and 15 red game tokens left.

How many children played this game?
If each child were to receive 3 more blue game tokens, then just as many blue as red game tokens would remain, i.e., 15 pieces. Thus, 48 - $15=33$ game tokens would need to be distributed. Since each child would receive 3 tokens, 11 children participated in the game.
