NMOS 2010 Q2

Q2. Adrian, Bryan, Charles, David, Elvin and Fedric played against one another in a singles tournament such that each one of them played every other player only once, and none of the games ended with a draw. If Adrian won 4 games, Bryan won 3 games, Charles won 2 games, David won 2 games and Elvin won 2 games, how many games did Fedric win?


6 x 5 / 2 = 15


15 - 4 - 3 - 2 - 2 - 2 = 2 games – won by F
