Help me solving this logical puzzle. I'm dumb as fuck.

You need to find the logical link to get the missing number.

12? The only thing I see the two complete groups having in common is that the sum of the outer numbers can be divided by the inner number.

@ltlian but there's a 1 in the second image...1 divides everything 😅. This can't be the correct logic...

@ceee I was thinking the same, but if there's one thing I've learned from these type of tasks is that the answer always, always makes you go "duh, seriously?.."

@ltlian lol

This one's either really hard, or it's plain stupid

The left and bottom triangle added together is always a square number: 16 for the first triangle, 49 for the second and 36 for the third. That looks like a trace. In the middle, there's always a square number.

What happens with their roots? First triangle: 4 and 5. Second triangle, 7 and 1. Uhm wait, if I add that up, that is 9 for the first triangle and 8 for the second, exactly what's in the upper left field!

Solution: 6+4 = 10 must be the missing number.

Oh, sorry I meant the RIGHT and bottom triangle, of course.

@Fast-Nop wow you nailed it 🕺

@Fast-Nop that was the correct answer.
Thank you very much!
