7 teams compete in a track competition. If there are 20 events in the competition, no event ends in a tie, and no team wins more than 3 events, what is the minimum possible number of teams that won at least one event?

3
4
5
6
7

I think the answer should be 7.

7 teams, 20 events, maximum 3 wins.

6*3 = 18

7th team will have to win the rest.

Therefore, 7.

Whats the OA?
