Question

2. If 70% of the students in a school are boys and the number of girls is 540, find the number of boys in
the school?

​

Answer 1

Answer :

Total number of boys in school are 1260 .

Step-by-step explanation :

Given :

• In a school 70% of the students are boys .

• Total number of girls = 540

To find :

• Total number of boys present in the school = ?

SoluTion :

Let us assume that the total number of students be x.

So,

➝ Total number of Boys = x - Total no. of girls

➝ Total number of Boys = x - 540

As it is given that, in a school 70% of the students are boys . So, the remaining 30% of the students would be girls.

which implies,

➟ 30% of x = 540

➟ 30/100 × x = 540

➟ 30x/100 = 540

➟ 30x = 54000

➟ x = 1800

Now, Total number of boys :

➝ 1800 - 540

➝ 1260

Hence, total number of boys in school are 1260 .
