Question

70% of the students in a
School are boys and
the number of girls is 504 then find the number of boys in the school
​

Answer 1

We know that, number of girls is 504. Let the totalnumber of students be x. Then, 30% of x = 504. Therefore, there are 1176 boys in the school.

Answer 2

Answer:

1176

Step-by-step explanation:

Suppose number of students be x, then

Number of boys = 70% of students.

So, number of girls =

(100-70)% of students

=> 30% of x = 504

=> 30/100 × x = 504

=> x = 504×100/30

=> x= 1680

Number of total students= 1680

So, number of boys =

(number of students)-(number of girls)

= 1680-504

= 1176

Hence, total number of boys is 1176.
