Is it 3)?

for I: x=100, y=5 and z=2 --> x>y>z (True)

for III: x=100, y=-5 and z=0 --> x>z>y (True)

I'm not seeing how II could be True.

I think I figured this one out. X &Y let me know what you think

II is true if we take 
z = 0.5
y = 0.3
x = 0.1

Z>Y>X

yeap, didint see that one.

OA should be "5"

It took me 30 mins to figure this one out. I seriously doubt that I will get something like this right on the test. 

But this was a good one. The questions in this new test are definitely trickier.

By the OA is 5 (i.e. I, II and III)

Thanks for your help X & Y
