I'll go with C...

From statement (1)...

If s=7 & r=2, n could be 6, 5, 4, 3...4 integers...
If s=7.2 & r= 2.2, n could be 7, 6, 5, 4, 3...5 integers...
Not sufficient

From statement (2)...

If s=9.9 & r=1.1...n could be 9,8,7,6,5,4,3,2...8 integers
If s=1.1 & r=0.9...n could be 1...1 integer
Not sufficient

Together...

Statement 1 tells us the range is 5...
Statement 2 tells us s & r are decimals, fractions, etc...
As long as the range is 5, the fraction or decimal for r and s must be equal...therefore, there will always be 5 integers between r & s...

Did I get it correct?

C for me too.

Statement I looked deceptively sufficient until I read Statement II.

I plugged in numbers too like mavery.

I agree vik, had statement 2 not been there, I probably never would have considered decimals or fractions...so much of what the GMAT asks about is integers, it's easy to get conditioned to forget about real #'s...

and more so in this question since it starts out by saying n is an integer so the integer status of r & s can to be taken for granted by many.

I think this is a good warm-up question.
