Students in a tournament (Posted on 2008-09-05) Difficulty: 2 of 5
Ninth- and tenth-grade students participated in a tournament. Each contestant played each other contestant once. There were ten times as many tenth-grade students, but they were able to win only four-and-a-half times as many points as ninth graders.

How many ninth-grade students participated, and how many points did they collect?

Note: one point for every win.

"This is another problem not clearly defined."

"What is supposed to be the point of the problem?"

Well, feel free to write to Mr. D. O. SHKLARSKY, or Mr. N.N. CHENTZOV, or Mr. I. M. YAGLOM, asking for cleareness (is this the word?) in theirs "selected problems and theorems of elementary mathematics". Probably you identified their names as russians.

Please, donīt forget to write me their answer.
