Question

In the International Grandmaster Championship, a total of 105 games were played where each team played exactly one game with all the other teams. How many teams were participating in the Championship?

Answer 1

Answer:

105*2=210 is your answer

Step-by-step explanation:

Logical analysis.

In a game of chess, 2 teams get to play in a game. So that means one game actually involves the two teams' gameplay which happens together.

For instance, let's say I am in Team A and you are in team B. So, if we were to play a chess game, then that means by that game, we both would have played our one game(our chance to play) each, also completing one official game(the games that are said in question).

So, if 2 teams give their chance to play 1 official game,

for 105 official games to happen, there would have been at least 105*2=210 teams to participate, since each team just gets one chance.

I hope you got it :)
