Answer 1

Step-by-step explanation:

given

70% of students are boys.

Then, 30% of students are girls.

( Because the total will be 100%)

We know that, number of girls is 504.

Let the total number of students be x.

Then, 30% of x = 504.

So, 30/100 * x = 504

So, x = 504 * 100/30

So, x = 1680 students

Then, the number of boys is 1680 - 504 = 1176

Therefore, there are 1176 boys in the school.

Answer 2

Answer:

The % of boys=70

the % of girls =30

So,let students in the class be x

30/100× x=504

x=1680

Total No of students= Total no of (Boys+Girls)

1680=504+Boys

boys =1176
