# Thread: Variables q r, s, t, u

1. ## Variables q r, s, t, u

If u > t, r > q, s > t, and t > r, which of the following must be true?

A. u > s
B. s > q
C. u > r

Hint: There are two answers from the given three choices.

I know that u and s are bigger than t. So, choice B is one of the answers. I also know that t is bigger than r. Since t is less than u, the other choice answer must be C.

My answer: Choice B and C.

Correct?

2. ## Re: Variables q r, s, t, u

Given:

u > t > r

then we may safely conclude:

u > r

Also:

q < r < t < s

Thus:

s > q

I don't see how we can infer A from the given information, so I agree with your conclusion.

That's another problem in the books.
