in a class there are 84 student . the number of boy is 2 times the number of girls .how many girls are there in the class​

28 girls.

Step-by-step explanation:

b - number of boys

g - number of girls

b = 2*g

b + g = 84

2*g + g = 84

3*g = 84

g = 84/3 = 28

And just in case:

b = 2*g = 2*28 = 56

b + g = 28 + 56 = 84; the answer checks out ;)

28

Step-by-step explanation:

Let the number of girls be x .

number of boys = 2x

Number of students in class =84

A/q,

2x +x = 84

3x =84

x= 84/3

x= 28

So number of girls in class is 28
