Answer 1

I think the answer is

0

Reason

For the 1st column, (∑yellow boxes-∑blue boxes=3) $$$$ For the 2nd column, (∑yellow boxes-∑blue boxes=2) $$$$ For the 4th column, (∑blue boxes-∑yellow boxes=5) $$$$ The only number left is 4 so that for the 3rd column, (∑blue boxes-∑yellow boxes=4), which is 1+6-3-?=4. $$$$ Therefore, ?=0
