Data Sufficiency

If m and n are consecutive positive integers, is m greater than n?
(1) m - 1 and n +1 are consecutive positive integers.
(2) m is an even integer.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficie
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficie
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficie
EACH statement ALONE is sufficie
Statements (1) and (2) TOGETHER are NOT sufficient

ANS A

Say m = 2 n = 3

m-1 = 1 n + 1 = 4 consecutive no ..m > n no

Say m = 3 n = 2

m-1 = 2 n + 1 = 3 consecutive yes ..m > n yes

Hence sufficient

From 2 we only know that m is even ..

n cud be anything ..

m = 2 n cud be 3
m = 2 n cud be 1

Hence insufficient
