(I had a prior post on FUNNY ANSWERS TO MATH OLYMPIAD QUESTIONS:
here. This one is a different problem.)
In 2000
I made up and graded the following problem from
the
Maryland Math Olympiad from 2007 (for High School Students)
There are 2000 cans of paint. Show that at least one of the
following two statements is true:
There are at least 45 cans of the same color.

There are at least 45 cans of all different colors.
It was problem 1 so it was supposed to be easy
95% of the students got it right and
I suspect everyone reading this blog can do it.
Note that the students taking this exam, Part II of a math
olympiad, did well on part I, so they are good students.
(Part I is 25 TOUGH multiple choice questions, point off
if you are wrong, and Part II is 5 problems that require proofs.)
I got two funny answers:
ANSWER ONE: Paint cans are grey. Hence there are all the same color.
Therefore there are 2000 cans that are the same color.
ANSWER TWO:
If you look at a paint color really really carefully
there will be differences. Hence, even if two cans
seem to both be (say) RED, they are really different.
Therefore there are 2000 cans of different colors.
Were they serious?
The first one points to a problem with
the phrasing of the question I clearly did not mean the
cans themselves, and all of the other students knew that,
but looking at the problem it could be interepreted that way.
This person might have been serious.
The second one I can't imagine was serious.
