am i missing something??

[Bronwyn]

if 0<r<1<s<2, which of the following MUST be true??

1. r/s

2. rs

3. s-r

shouldn't it be 1 AND 2??

the answer however is only 1

two things:

(1) you have not cited a source for this problem. if you don't do so, we'll have to delete the problem within a few days.

(2) the problem has apparently been transcribed incorrectly: the choices are most definitely not things that can be 'true' or 'false'.
either the prompt question or the choices must be different; take a look again and re-post (along with the source).

if this happens to be a GMAT PREP question, then re-post it in that folder.

thank you.

this is exactly how the question is phrased. I got the problem from my instructor and it is from mba.com gmat prep. is there confusion in the fact that i used 1,2,3 instead of numericals??

The question is not complete. You'd have to say something like: which of the following must be even? Or which of the following must be positive? It doesn't make sense simply to say "is r/s true?" What about r/s must be true?
