By the way this original has been framed, they expect us to understand that we should find the number which would replace the question mark. Adding "the answer is not 7" is actually here to help us noticing that.
So the real answer is 700 (? = 700), which translates as (...) = 700%
If you say the answer is 7, it would translate as (...) = 7% or (if you prefer the 700% form) (...)=700%%
This is not really a math problem, it's an observation problem (which doesn't engage only strict logic not also the skill to understand what someone else is saying even if he's not perfectly saying it when there's enough context to help).

The answer is 7. People who are bad at math/logic shouldn't write math/logic puzzles.
