Answer 1

Boys and girls

As there are 3 boys and 2 girls in the group, only 1 game was played between a girl and a girl.

Since a group of friends played chess, and each person played exactly one game with each other in the group, and out of the total number of games played, 3 games were played between a boy and a boy, and 6 games were between a boy and a girl, to determine how many games were played between a girl and a girl, the following calculation must be performed:

• 2 players = 1 match
• 3 players = 3 games
• 6/3 = 2

Therefore, as there are 3 boys and 2 girls in the group, only 1 game was played between a girl and a girl.
