Answer 1

Answer:

5

Step-by-step 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. 5 kids are in bare feet.

Answer 2

The number of kids in bare is 5.

Given:

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

To Find:

The number of kids is bare.

Solution:

To find the number of kids are in bare we will follow the following steps:

3 kids are wearing both socks and shoes.

So, Out of 6 students wearing socks 6-3 = 3 students are wearing only socks.

Similarly, out of 4 students wearing shoes 4-3 = 3 students are wearing only shoes.

Now,

Numbers of kids bare = total number of kids - number of students wearing only socks - number of students wearing only shoes -number of students wearing both socks and shoes.

So,

Numbers of kids bare = 12-3-1-3= 5

The square root of 5 =√5 = 2.23

In the above figure, AB is 1 and AO is 2²= 4

Using Pythagoras theorem.

OB² = OA² + AB²

5² = 1²+2²

So, OB is 5 as represented on a number line.

Henceforth, the number of kids barefoot is 5.
