Answer:
Total student of boy class 10th = 400
And, girls = 25%
No.of the total girls student = 400×25÷100
=100
Hence, the total student of girls = 100
And, boys = 400 + girls
= 400 + 100.
= 500
So, total student of school = 500

total boy students = 400
percentage of boy students = 75%
total students = x
75x/100= 400
x=400*100/75
x=533.33 or 534
hence there are approximately 534 students in total 10th grade
