(2) n/5 is an even integer.

Is the integer n even?
(1) n – 5 is an odd integer.
(2) n/5 is an even integer.

1) n could be an even integer or 0. So INSUFF

2) If n is the product of 5 and an even integer, n is even. SUFF

Answer is B.

Answer is B.

The question says is the "INTEGER" n so if n-5 is odd n will always be even.. I think the answer is D

[radhika1306]

OA is D

[ratindasgupta]

Well 0 is an integer. So unless u assume 0 as an even integer, statement 1 is insufficient.

0 IS an even integer.

ya the ans must be D

Stmt 1: if you subtract an odd nos from an even nos the result will always be odd and ofcourse 0 is even(universally excepted, also on the GMAT) hence SUFF

Stmt 2: 5 multiplied by an even nos will always give a number ending in 0 hence even SUFF

Q says n/5 is an even integer & 4/5 is not an integer hence we cannot consider n as 4 or any nos which is not divisible by 5
