Barefooted Kids

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?

Answer

5 kids are bare feet.

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 kids are there, so, 12 – 7 = 5.
