Answer 1

Answer:

i think 21 girls and 21 boys

Answer 2

$\large{\bold{\boxed{Answer\: =\: 14 \:girls}}}$

Given That -

Number of Student in a class = 42

Number of Boys = 2 times the number of girls ( 2 $\times$ no.of girls )

Solution -

Let number of Girls = 'X'

And $\therefore$

Number of Boys = 2x

Now it's given that total number of students = 42 = Number of boys + Girls

that is -

Boys + Girls = 42

$\implies$ 2x + x = 42

$\implies$ 3x = 42

$\implies$ x = $\dfrac{42}{3}$

There for we have --

X = 14 = Number Of Girls
