There are 12 teams in a certain league and each team plays each of the other teams exactly twice. If each game is played by 2 teams, what is the total number of games played?
Answer/Solution
132
Steps/Work
Every team plays with 11 teams...so total no of matches = 12 x 11 = 132.
Now, each match is played twice => 132 x 2
But 2 teams play a match => 132 x 2 /2 = 132.
Answer: E
