Missing number

Post by Kirk Bevins » Mon Jul 07, 2014 4:34 pm

5 9
6 4


2 3
8 4


2 7
3 3


1 5
3 ?

What's the missing number? I think 2 but my logic is pretty poor. Anyone got a better answer and reasoning?

Is the third square definitely right? I thought the missing number might be 5, but that only works if the bottom right number of the third square is a 1.

Well that's what the magazine shows it as so I have to assume it's right

Ha, you were probably spot on. They've released the "answers" this week. All they've said is there was a typo in last month's edition but not given the answer! Well done.
