<h2><u>
Boys and girls</u></h2>
<u></u>
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.

2/3(120) = 240/3 = 80 do not drink
4/5(120) = 480/5 = 96 do not smoke
72 do not smoke or drink
96 - 72 = 24 do not smoke
80 - 72 = 8 do not drink
72 do not do either
120 - (24 + 8 + 72) = 120 - 104 = 16 drink and smoke
