Please help me on below questions, it is from test-01, thank you very much.
Fora certain race, 3 teams were allowed to enter 3 members each. A team earned 6– n pointswhenever one of its members finished in nth place, where 1 ≤ n ≤5. There were no ties, disqualifications, or withdrawals. If no team earnedmore than 6 points, what is the least possible score a team could have earned?
the right answer is "3"

痴人也有梦

5,4,3,2,1 = 15
least possible score:  15 - 2*max= 15- 2*6=3

1st team : 5,1
2nd team: 4,2
3rd team: 3
