If m and n are consecutive positive integers, is m > n?
1. m - 1 and n + 1 are consecutive positive integers
2. m is an even integer
1. m - 1 and n + 1 are consecutive positive integers
2. m is an even integer
IMO A
St 1 says m-1 and n+1 are consecutive
This condition is true for all consecutive numbers where m>n
you can pick numbers and check: let m=11 and n=10
M-1 = 11-1 = 10
N-1 = 10+ 1 = 11
St 2 is Insuff as it gives no information about n.
So A alone is SUFF
