During the chess tournament, each participant played 24 games as a school champion, won 12 games and drew. Three fewer games the rest lost How many games did he lose?

Under the conditions of the problem, we were told that the champion of the school won 12 games, and drew three games less, based on these data, we have the first action:

1. 12 – 3 = 9 games were drawn by the school champion.

The second step is to find out how many games were won and drawn together:

2. 9 + 12 = 21 games the champion won and brought to a draw.

And since we know that in total each participant played 24 games, we can find out how many games the champion lost:

3.24 – 21 = lost 3 games.

Answer: 3 games.
