Question

The ratio of boys to girls in school is it 3 ratio 2 if there are 600 boys in the school, the find the number of girls.

Answer 1

Answer:

400

Step-by-step explanation:

Let the total number of students be x.

Boys=3/5x

Girls=2/5x

3/5x=600

1/5x=200

2/5x=400

Answer 2

Given :

• The ratio of boys and girls = 3:2
• Number of boys = 600

To find :

• The number of girls

Solution :

• Number of boys + Number of girls = Total students.

:$\implies\sf{Let, \: the \: number \:of \: boys \: be \: 3x}$

:$\implies\sf{And \: the \: number \:of \: girls \: be \: 2x}$

:$\implies\sf{x = \: \frac{600}{5}}$

:$\implies\sf{x = \: \frac{\cancel{600}}{\cancel{5}}}$

:$\implies\sf{x=120}$

• Now, number of girls = 2x
• Girls = 2 × 120
• Girls = 240

Hence, the number of girls is 240
