2012 Squad Assignment One – Combinatorics

This year’s team selection will again be based on three competitions (the BMO2, the AMO, and the APMO) and four assignments: one on each of the four Olympiad areas of algebra, combinatorics, geometry and number theory.

Here is the squad’s first assignment, on combinatorics. I’ll post the solutions in about a month, together with the second assignment, on algebra. Following our usual practice, you can get the solutions before then if you write to me with evidence that you’ve made a serious attempt.

Have fun!

Here is one of several training tests. These problems are intended to be quite hard, but several should be accessible to experienced students; all these problems are at a level expected at the IMO. Notice however that the problems are not in order of difficulty!

 

Solutions will follow a little later.
