The Bare Feet Kids-Math riddle


There are 12 kids in a classroom. 6 kids are wearing socks and 4 are wearing shoes. 3 kids are wearing both.

How many are bare feet?

 

Explanation :  

As we know 3 kids are wearing both, 
So only 3 kids are wearing only socks(6 - 3 = 3) 
and 1 is wearing only shoes(4 - 3 = 1).
So, in total 3 + 3 + 1 = 7.
Now 12 are there, so 12 - 7 = 5 kids are in bare feet.
