Question

A tournament where every team plays with every other team once and the number of matches is determined with the help of the formula \(N(N-1)\) is called as:

• A. knockout tournament
• B. double league tournament
• C. single league tournament
• D. none of these

Hint:

In a single league tournament, every team plays each other once, and the formula \(N(N-1)\) calculates the total number of matches.

Answer 1

The Correct Option is C

In a single league tournament, each team plays against every other team exactly once. The formula \(N(N-1)\) calculates the total number of matches, where \(N\) is the number of teams in the tournament. Step 1: Analyzing each option.

• (A) Knockout tournament: Incorrect. In a knockout tournament, each team plays only once and gets eliminated after losing a match.
• (B) Double league tournament: Incorrect. A double league tournament involves teams playing against each other twice, but the formula provided is specific to a single league tournament.
• (C) Single league tournament: Correct. In a single league tournament, every team plays each other once, and the formula \(N(N-1)\) calculates the total number of matches.
• (D) None of these: Incorrect. The correct answer is (C).

Step 2: Conclusion.
Thus, the correct answer is (C), single league tournament. Final Answer:} Single league tournament.
