Answer 1

Step-by-step explanation:

The ratio of the number of boys to girls in a school is found to be 3:2. If there are 300 students in the school, find the number of boys and girls in the school.

Answer 2

Correct Question:-

Given:-

• Ratio of boys and girls = 3:2
• Total number of students = 300

To Find:-

• Number of boys and girls

Solution:-

Put x in the ratio,

• Number of boys = 3x
• Number of girls = 2x

According to question,

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: 3x + 2x = 300}$

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: 5x = 300}$

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: x = \frac{300}{5} }$

$\large{ \tt \longmapsto \: \: \: \: \: \: \: \: \: x = 60}$

Now,

• Number of boys = 3x = $\bf{ \red{ \boxed{180}}}$
• Number of girls = 2x = $\bf{ \red{ \boxed{120}}}$

Hence,

• The number of boys and girls are 180 and 120.
