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(4): Big hint, almost a spoiler by tomarken)

You are right, tomarken.  I don't know how I missed that.

I, too, assumed that the score was for one team but could not find a solution, so I figured I might try it for each team.  Yet it sems that does not resolve it either.

I guess if you were a Knave, Liar, or a mistaken Knight, you could say there must have been four tries with the smallest score being 0 (zero).
