Question

5. In a co-educational school, 45% of the total students are girls. If there are 440 boys in the school, find the number of girls in the school. ​

Answer 1

Answer:

Given Number of girls = 45%.

Number of boys = 55% = 440.

if 55% = 440

Then 1% = 440/55

Then 45% = (440*45)/55

= 360.

Number of girls in the school = 360.

Answer 2

Given:

• Girls = 45
• Boys = 55%

Solving :

Let number of students be x

number of boys = 440

• 55% of x =440

x=440*100/55=800

Hence, number of girls = 800-440=360
