In a tournament, each team plays one match against every other team. A total of (153) matches were played. How many teams were there?

Explanation opens after your attempt
Correct Answer

B. (18)

Step 1

Concept

Let the number of teams be (n). Then (\frac{n(n-1)}{2}=153). This gives \(n^2-n-306=0\), so (n=18).

Step 2

Why this answer is correct

The correct answer is B. (18). Let the number of teams be (n). Then (\frac{n(n-1)}{2}=153). This gives \(n^2-n-306=0\), so (n=18).

Step 3

Exam Tip

टीमों की संख्या (n) हो तो (\frac{n(n-1)}{2}=153)। इससे \(n^2-n-306=0\) और (n=18) है।
