Question

b. In a school of 500 students, the number of boys is 4 times the number
of girls. Find the number of boys and girls.​

Answer 1

Answer:

Given

Total number of girls = 100

Number of boys = 4 / 5

Let us assume the total number of boys and girls be x

Total number of boys = 4 / 5 of x

We get,

= 4x / 5

According to question, total strength of school can be calculate as below

Number of boys = Total strength – Girls

= 500 – 400

= 400

Hence number of boys are 400

Answer 2

Given :

In a school of 500 students, the number of boys is 4 times the number of girls.

To find :

• Number of boys and girls

Solution :

Let the number of girls be x and number of boys be 4x

• Total number of students = 500

According to question

→ Number of girls + number of boys = Total number of students

→ x + 4x = 500

→ 5x = 500

→ x = 500/5

→ x = 100

•°• Number of girls = x = 100

•°• Number of boys = 4x = 400
