Question

If 36% of pupils in a school are girls and the number of boys in the school is 816 ,how many girls are there in the school?​

Answer 1

Answer:

The total number of girls in the school  are 459.

Step-by-step explanation:

Let x be the total number of students in the school.

It is given that 36% of the total number of students in the school are girls.

⇒Percentage of Boys = 100% - 36%

                                     = 64%

It is also given that the number of boys in the school is 816.

⇒ $\frac{64}{100}$ × $x$ =816

⇒ $x$ = 816 ÷ $\frac{64}{100}$

⇒ $x$ = 816 × $\frac{100}{64}$

⇒ $x$ = 1,275

∴ The total number of students in the school is 1,275.

∴ Total Number of Girls = $\frac{36}{100}$  × 1275

                                         = 459.

The total number of girls are 459.

 

Answer 2

ANSWER:-

459

Step by Step Explaination :-

Let the number of Girls In the class be "x"

Given:-

Percentage of girls = 36%

Number of Boys = 816

To Find:-

Number of GIRLS.

Solution :-

According to Question :-

with the Basic concept of Percentage,

we know that,

=> Percentage =( no. of x/ total x+y )x100

Using this simple equations,

we see that,

$= > \frac{x}{x + 816} \times 100 = 36$

Since, using the basic laws of percentage.

Now,

=> 100x/[x+816 ]=36

=> 100x=36x+29376

=> 64x=29376

=> x= 29376/64

=> x= 459

So, the number of girls in the class is 459 and boys is 816.
