For a Rugby Union game, what's the smallest score that allows you to say that there must have been at least four (converted or not) tries?

"20" isn't the correct answer, because you could have managed it with two converted tries and two penalties. "21" isnīt it either, for three converted tries suffice, and "22" also doesnīt work, for you can manage it with less than 4 tries.

NB. The scoring is: 3 for a drop-goal or penalty kick. 5 for a try, and 7 for a converted try (A converted try is when a try has been scored, and the team that scored kicks the ball between the posts.)

(In reply to re(3): Big hint, almost a spoiler by Dej Mar)

I interpreted the problem to mean the total points for one team.  The examples given in the puzzle refer to only one team's score.

In any event, a score of 14-14 could be acheived if each team scored one try (5) and three drop-goals (3*3 = 9).
