If x<y, y<z and z>w, which of the following is always true?
A. x>w
B. x>z
C. y=w
D. y>w
E. x<w


OA is B, which I don't think is right.
Can any one confirm this?

I'm pretty sure the answer is E.. I think the OA is wrong as well.

It seems that all the answer choices are incorrect. Since we only know that z>y>x and also z>w we cannot compare x or y with w since w might be >y or =y or =x or >x or <x or <y any of these is possible. Hence all the answer choices with w cannot be possible.

B x>z is surely wrong as we know that x<y and y<z hence z must be z>x.
