1 s - r =5
2 r and s are NOT integers
Thanks (Should I classify this problem as Number Property?)
stat 1. Not sufficient. If s and r are integers, there will be 4 integers between r and s (Ex. s = 6, r = 1). If r and s are not integers there will 5 integers between r and s (Ex. s = 6.9, r = 1.9).
2. Not sufficient. r and s could be any numbers
1 and 2 - There will be 5 integers between r and s
hence it should be C
