x<0<y+z

z!=0

Quantity A	Quantity B
(y+z)/x	y/z

A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.

Here we can see that \(z\neq 0\). So z can either be 0 or 1.

Depending on the value of z Quantity B can be finite or infinite (as y cannot be 0 such that y/z can be written in 0/0 form).

Thus option D is the only possibility.

My answer was D. In response to the above, I assume that z! = 0 means z x z-1 x z-2 etc. so the only number that makes sense here is that z MUST equal 0. In that case option B above is an illegal number (since you can't have 0 in the denominator). Quantity A will always be negative because x is negative. I am not sure though how z! could equal 1 as per the above response?
