91% (00:25) correct
8% (01:37) wrong based on 70 sessions

X + Y = - 1

Quantity A

Quantity B

X

Y

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.

Another approach is to TEST VALUES that meet the condition that X + Y = -1

Let's try X = -2 and Y = 1 In this case, we get: Quantity A: -2 Quantity B: 1 So, Quantity B is greater, which means the correct answer is either B or D

Now let's try X = 1 and Y = -2 In this case, we get: Quantity A: 1 Quantity B: -2 This time Quantity A is greater, which means the correct answer must be D
