solve 20 number questions please the answer of the questions is10 girl , 30 boy​

Answer 1

Answer:

Number of Boys in the class = 30   and

Number of Girls = 10.

Step-by-step explanation:

here, Total number of students in class = 40

now, Let the number of boys = $x$

so, The number of girls = $\frac{x}{3}$

According To the Question,

⇒ $x + \frac{x}{3} = 40$

⇒ $\frac{3x + x}{3} = 40$

⇒ $4x = 40 * 3$

⇒ $x = \frac{40 * 3}{4}$

⇒ $x = 30$

∴ Number of Boys in the class = 30

and, Number of Girls = 40 - 30 = 10.

hope it will help you.

Answer 2

let the number of boys be x and that of girls be x/3

we know that,

number of boys+number of girls=40

x+ x/3 = 40

4x/3 = 40

4x = 40×3

x = 120/4 = 30

number of boys= x = 30

number of girls =x/3 = 10

hope my answer helps you! ♡
