Question

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

No. of girls=360

Step-by-step explanation:

Let the total number of students in the school be x

If girls are 45% so boys will be 55%

ATQ

55% of x=440

x=(440*20)/11

x=800

so total students in the school are 800

Girls=Total Students - Boys

Therefore,

Girls=360

Answer 2

$\huge\green{\fbox{\fbox{\red{\mathcal{Bonjour}}}}}$

percentage of girls=45%

percentage of boys =55%(100%-45%)

number of boys=440

$1\% \: girls \: = \frac{440}{55}$

$= > 1\% \: of \: girls = \frac{8}{1} \\ = 8$

$45\% \: of \: girls \: = 8 \times 45$

$= 360$

hope this helps you xD
