Puzzle - How many kids are in bare feet?

[tigershark]

Five kids are in bare foot.
Because 3 kids are wearing both, 1 kid is wearing only shoe and 3 kids are wearing only socks, so that makes 3 + 3 +1=7 kids, wearing either shoe or socks.

Hence 12-7= 5 kids barefooted

I second Contractor.

Five

You all right.
