Answer 2

Given - Percentage and number of girls = 60% and 690

Find - Total number of student and number of boys in school

Solution - As per the question, 60% of students in school are girls, which is equal to 690. Taking the total number of students to be x.

So, 60/100*x = 690

x = 690*100/60

x = 1150

Now, total number of students are 1150. Out of these, 690 are girls. Therefore, total number of boys in school are = 1150 - 690

Total number of boys = 460

Hence, total number of students in school are 1150 and total number of boys are 460.
