3)   16 teams participated in a cricket tournament.

The tournament was conducted in two stages.

First stage
  • In the first stage, the teams are divided into two equal groups.
  • Each team plays every other team in its group exactly once.
  • At the end of first stage, the top four teams from each group advance to the second stage.
  • Rest teams are eliminated.
Second stage
  • The second stage comprised several rounds.
  • A round involves one match for each team. The winner of a match in a round advances to the next round, while the loser is eliminated.
  • The team that remains undefeated in the second stage is declared the winner and claims the Gold Cup.
Rules
  • The tournament rules such that each match results in a winner and a loser with no possibility of a tie.
  • In the first stage, a team earns one point for each win and no points for a loss.
  • At the end of the first stage, teams in each group are ranked on the basis of total points to determine the qualifiers advancing to the next stage.
  • Ties are resolved by a series of complex tie-breaking rules so that exactly four teams from each group advanced to the next stage.
What would be the total number of matches in the tournament?


a. 55
b. 56
c. 63
d. 66
Answer  Explanation 

ANSWER: 63

Explanation:
In first stage, teams are divided into two groups of 8 teams each.
They play a match against everyone exactly one i.e. 8C2 matches in every group.

So,
2 x 8C2 = 56 matches for the first stage.

8C2 = 8! / (2!)(6!) = 4 x 7 = 28

In second stage, there are 8 teams in a “knockout stage”.
There will be one winner, so 8 – 1 = 7

So, total number of matches is 56 + 7 = 63
