4/9 of students are boys
so no. of girls will be 1-4/9 = 5/9of total students
5/9 of total students = 775
total students = 775*9/5
= 1395
no. of boys will be 4/9 *1395
= 620
so no. of girls will be 1-4/9 = 5/9of total students
5/9 of total students = 775
total students = 775*9/5
= 1395
no. of boys will be 4/9 *1395
= 620
