उत्तर
n (K -2)
Explanation:
Number of teams = n(n > 5)
Number of player in 1 team = K(K > 3)
Now, consider team 1
It has number of player = k (k > 3)
Now, number of player common with the other team (Tn ,T2) = 2
So, number of uncommon player in each team = K –2 and number of teams = n
∴ Total number of players = n (K–2)
