​

Answer 1

Step-by-step explanation:

We have

Total no, of students is the class =40

Let No. of girls be x

Then No, of Boys =3x

Now

No. of boys +No. of girls =40

3x+x=40

4x=40

x=10

Hence the no. of girls in the class is 10.

The only difference is that we find out how many girls. Once we have the numbers of girls, we can then subtract the girls from the total number of students to get the number of boys.

GIVEN :-

Total number of children = 40%

TO FIND :-

Find the Number of Girls.

SOLUTION :-

Total Number of Children = 40%.

So,

Number of Girls = (40/100)×40 = 16 girls

40–16 = 24 boys
