If n and kare positive integers, is n/k an even integer?
(1) n is divisible by 8.
(2) k is divisible by 4.
A.Statement (1) ALONE is sufficient, but statement (2) alone is notsufficient.
B.Statement (2) ALONE is sufficient, but statement (1) alone is notsufficient.
C. BOTH statementsTOGETHER are sufficient, but NEITHER statement ALONE issufficient.
D. EACHstatement ALONE is sufficient.
E.Statements (1) and (2) TOGETHER are NOT sufficient.
参考答案：E
题目翻译：如果n和k都是正整数，那么n/k是不是偶数?
题目全解：First off, neither statements are sufficent alone b/c each provides info about one of the variables.
Putting the statments together--pick multiples of 8 for n and 4 for k:
n=8, 16, 24, 32, 40, 48 etc.
k=4, 8, 12, 16, 20, 24, 28, etc.
So, put the statements together:
-If n=8 and k=4-->2-->even
-If n=8 and k=8-->1-->odd
INSUFFICIENT. Choice E.
