Hi,

I think the OA is wrong here. If x=y=0, then the ratio is undefined (or at least not 1:3). Am I missing something?

Best regards

You are absolutely right, it should be mentioned in the stem that x is a non-zero number in order the answer to be A.

Concept is Ratio
y : x or y/x =?
1, y/x = 3/1
2, No
So A

But what is all about this x=y=0 and data missing??
I am missing any concept??
