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.
Given:
xy is POSITIVEyz is NEGATIVEDivide them to get:
xy/
yz =
POSITIVE/
NEGATIVESimplify the left side to get: x/z =
POSITIVE/
NEGATIVESimplify the right side to get:
x/z = NEGATIVEIf x/z is NEGATIVE, then one value (x or z) is POSITIVE, and the other value is NEGATIVE.
If one value (x or z) is POSITIVE, and the other value is NEGATIVE, then xz = (POSITIVE)(NEGATIVE) =
NEGATIVEWe get:
QUANTITY A:
NEGATIVEQUANTITY B: 0
Answer: B
