70% of the students in a school are boys and the number of girl is 504 . Find the number of boys in the school.
Answer: 1176
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.
