15 is what times more than 5 ??????

I have a question which is quite confusing....

15 is what times more than 5 ?

Does the answer should be 2 times or 3 times because we generally as a mathematician say it is three times more than 5. but three times of 5 is 15 and 2 times of 5 is 10.

we can otherwise say 15 is 10 more than 5 alas 15 is 2 times more than 5.


But ask any mathematician the answer is 15 is 3 times more than 5.

Solve the problems mathematically not linguistically.I am not sure what the answer will be,but if a problem like this comes I will blindly write the answer as 15 is 3 times more than 5 because this is what my teachers told me and I am following it.

If you ask me about my opinion off the record I say

15 is 2 times more than 5

or

15 is 3 times of 5
