要参加GMAT考试的考生大部分需要经历一个备考阶段，在这个阶段内部断的充实自己的知识并不断的进行检验，检验的最好方式就是练习，为了便于大家更好的备考，小编为大家带来了GMAT备考资料之
1、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.

参考答案：C
题目翻译：有等式(12^x)[4^(2x+1)] = (2^k)(3^2)，其中k和x都是整数，求k。
题目全解：(1) Says T- 4n = 23 Insuff
(2) says T-6n = 5 Insuff
Together find n and arrive at T
Hence C
