Q18:
If q is a positive integer less than 17 and r is the remainder when 17 is divided by q, what is the value of r?
(1) q > 10
(2) q = 2k, where k is a positive integer.


the answer is B,but I cannot realize the answer by repeatly thinking because I choose C

[Penny Lee]

The statement (2) should be q=2^K, where k is a positive integer.

The question is what the remainder is when 17/q,

(1) 17>q>10, q=11,12,13,14,15,16, r=6,5,4,3,2,1, not sufficient

(2) q = 2,4,8,16, r=1, sufficient

My answer is B.
