Hi! I could not solve this…

Big Book - Test 12 - Section 1 - Exercise 8

It states that

X>Z

Y>Z

The option A is X+Y

The option B is Z

Question: For me its obvious that the anwer is A, but actually is D. Can someone help with an example that Z could be equal or higher than X+Y?

Thanks!

Assume X, Y & Z are negative and X =-1 ,Y= -1.5 while Z = -2 .

Given,

X=-1 > Z=-2 —True

Y= -1.5 > Z= -2 – True

Now looking at Qty A

X+Y which is -2.5

and Qty B

Z which is -2 —> Here Qty B> Qty A and as u said u already figure out the values for making Qty A> Qty B. Hence, our ans is D

Thank you so much! Helped a lot!
