Why do I feel like this has become Benq's mock competition, not Th3Numb3rThr33's mock competition?

Ahahaha @ nosaj.

I really have gotten lazy (and by lazy I mean laaaaaaaaazeeeee), and sorta lost my muse. So yeah, that's why I'm not so active anymore. XD

Just a quick fun fact, the National Competition and the State COmpetition were so mixed up, I think we switched the tests. XD

Do you mean "At least how many students must be the same age as another?" or what

or a better way to word it would be "find the minimum value of the maximum number of students that are of the same age as another?"

Okay, that is a big problem. Then Nats will be easier than States? The State test did seem much harder than the chapter one, now I see why…

P.S. You're welcome Th3Numb3rThr33 for changing "Competition" in the quote.

EDIT: Maybe the imaginary parts got lost somewhere in the computation in my link, seeing as they are rather small.

Darn this is a lot harder than the actual thing so idk. People scored $\approx 15$ points worse on this than on the actual state competition (of course, excluding joey8189681

).

Not to revive, but how did they arrive at the solution for number 26 on sprint? Seems ingenious.

Is there a similar way to do the problem if instead of $a\leq{b}\leq{c}\leq{d}$ it was $a<b<c<d$ ?

Then you could simply do $\binom{9}{4}=126.$

It's on the very hard side of Nationals, but all the problems are definitely solvable using techniques that can be applied to other problems and do not require knowledge not expected of Mathcounts participants

This competition lowered my self-confidence for making State CD by about 60%. Thanks for making it still!

I totally agree with this. It took me a minute or more for the first few questions(1-10) and I couldn't get any of the later questions. This could be nats level (It seems like it) or it could also be used as practice for 9-10th graders who have done MC previously.
