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.

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 .
