A chess player played 20 games in a tournament and scored 12.5 points. How many more games did he win than he lost?

#
If a chess player had an equal number of wins and losses, he would have scored 10 points (the same as if he had drawn all 20 games). Since in reality he scored 2.5 points more, five draws need to be replaced by five wins, meaning the chess player has 5 more wins than losses.

## Answer

By 5 games.
