If one equals two,
What does seven equal.
That's one possible solution I hope
I personally hate this type of question. One clearly does not equal two - f(one) may equal f(two), but that's not the same thing. My default answer would be that one doesn't equal two, so, in that case (which doesn't exist), seven can equal whatever you want it to. It's a bit like religion - accept enough made-up claims, and you can deduce anything.
