Re: DS Inequality 3 [#permalink]
29 Mar 2005, 18:54

from (1), s could be any integer or any number so does r. n varies with the values of s or n.
from (2), it is clear that r and s are not integers but we do not know what are the values of r and s.

from 1 and 2 only we know that there are 5 integer values for n.

Here's my re-worked solution. Sorry, I alway forget about integers...

1) Not sufficient. If s and r are integers, then n=4. However, if s and r are not integers, then n=5

2) r and s are not integers. Not sufficient. s and r can be sets of different values, giving no definite value for n.

1 + 2--> Tells us r and s are not integers, so n=5.

Ans:C

That's my problem too. I tend to forget about integers and non integers. There is this force in me that keeps assuming everything is an integer. arrrrrrrrrrrrrrrrrrrrrrrrggh!

"GMAT is out to trick you with integers and non-integers ", if you keep this in back of your mind whenever you see a DS with variables then you will be better off.

Actually, if you've forgetten that r and s can be non integer when you look at (1), (2) should serve as a very good reminder for you and you should immediately realize that you need to revisit the question from the beginning.
