How do we define a question the average 12 year old can answer? Average American 12 year old is different than the average Kenyan 12 year old.

Good question...

I have a 12 yr old brother I'll let him be the judge.

for example the question about the couple, 8 sister with 1 brother, he answered 18 haha. so that's obviously not 12 yr old material.

Just ask a very simple question that anyone can answer.

if you are still not sure.
why don't u ask a question that a 6 yr old can answer? then that way any 12 yr old can answer for sure.
