A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Let's test some values
Try z = 1
we get:
Quantity A: 99(1)/100
Quantity B: 100/99(1)
Evaluate:
Quantity A: 99/100
Quantity B: 100/99
Here, Quantity B is greater
Try z = -1
we get:
Quantity A: 99(-1)/100
Quantity B: 100/99(-1)
Evaluate:
Quantity A: -99/100
Quantity B: -100/99
Here, Quantity A is greater
