Answer
Given,
Boys : Girls = 9 : 5
Let number of Boys = 9x and Girls = 5x.
Total number of girls in school = 425
So,
⇒ 5x = 425
⇒ x =
⇒ x = 85.
Therefore,
Number of Boys in school = 9x = 9(85) = 765.
Total number of students in school = 765 + 425 = 1190.
Hence, the total number of students in the school = 1190.
