Quantity A: x
Quantity B: y
Quantity A: x
Quantity B: y
Let's test some values:
We need values of x and y that satisfy the equation x + y = -1
case a: x = -1 and y = 0
Here, we get:
Quantity A: -1
Quantity B: 0
In this case, quantity B is greater.
case b: x = 0 and y = -1
Here, we get:
Quantity A: 0
Quantity B: -1
In this case, quantity A is greater.
Answer: D
