Answer 2

Question :

In a school, there are 300 students. Out of them, there are 20% girls. find the number of boys and girls in school.

Answer:

• Number of girls in school is 60
• Number of boys in school is 240

Step-by-step explanation:

GivEn:

• Total students in school = 300
• No. of girl in school = 20%

To finD:

• Total number of girls in school
• Total number of boys in school

Solution:

We have given that total number of students (number of girls+number of boys) = 300.

Finding number of girls :

Number of girls = 20% of 300

=> Number of girls = $\small{\bf{\frac{20 \times 300}{100} }}$

=> Number of girls = 20×3

=> Number of girls = 60

So, the number of girls in school is 60

Finding number of boys :

We know that total students in school is 300 and number of girls in school is 60. So the numbers of boys in school can be calculated by subtracting the number of girls from total students.

→ Number of boys = Total students - Number of girls

=> Number of boys = 300 - 60

=> Number of boys = 240

So, the number of boys in school = 240
