Answer :

total no of childrens in the group=48
let total girls present in the group be x
by the question,there are twice as many boys as girls
therefore,
           boys=2x
now,2x+x=48
     ⇒ 3x=48
      ⇒x=48/3
        ⇒x=16

therefore, there are 16 girls in the group.

The number of boys are 32 and girls are 16 in a group of 48 children .

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.

According to the question

Let boys = B

and  girls = G

Now,

A group of 48 children that contains boys and girls  

in equation

B + G = 48 -------------------(1)

there are twice as many boys as girls

in equation

B = 2G ----------------------- (2)

Now ,

Putting the value of B in equation in (1)

B + G = 48 -------------------(1)

2G + G = 48

3G = 48

G = 16

B = 32

Hence, The number of boys are 32 and girls are 16 in a group of 48 children .
