OG question

Question no 153 in OG_11 in DS section sounds little bit tricky to me. In order to learn the concept and trick behind this type of question, I framed 2-3 extra questions.
Q1: Does the integer K has a factor p such that 1<p<K?
A: 12x+2<=K<=12x+5.
B: x is even integer.
Q1: Does the integer K has a factor p such that 1<p<K?
A: K>4!-2!
B: 11!+3 <=K<=11!+11
Q1: Does the integer K has a factor p such that 1<p<K?
A: 3!<K<4!
B: K=x+2. Where x is a multiple of 4.

Hope I framed all the question appropriately. If not, please point out.
