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:
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
