More Brain Teasers

Since I'm probably wrecking my brain over math problems in Bangi, here's some IQ questions for you too! *Smiles wickedly* Don't worry I'll post solutions along with the previous ones when I come back.

 

Hints:

Example 2.1.3 is a popular IQ question and it's not hard, just don't limit yourself too much. The same applies to the rest. To be honest, only 2.1.4, 2.1.6, 2.1.8, and problem 9 requires math. Some of the questions are kinda...... cold-joke styled. Freezing, in fact. Well, have fun.
