Wrong Answer

Question on a Daily Brain Teaser on the Internet: "What is the smallest number that, when written out, uses all the vowels, A, E, I, O, U and even Y one and one time only each in its spelling?"

I both enjoy and hate these questions, because usually the proposed answer is incorrect due to the question's looseness.

For example, the proposed answer to the above question was "sIx thOUsAnd twEntY."

And, why is this not correct? Because, what about the smaller numbers "twEntY-sIx thOUsAndths" or even "two - twEnty-sIx thOUsAndths."

Don't cry fOUl too fast on me....
