595

Explanation:

Percentage of girls = 30%

30% = 255

Total number of students (x):

x(30/100) = 255

x = 255(100/30)

x = 850

Total number of students = 850

Number of boys = 70% of the total students

                           = (70/100) 850

                           = 85 × 7

Number of boys = 595
