1. Answer:

   Let “x” be the total no. of students. But we are given that the number of girls in the school is 775. Thus, the number of boys in school is 620.

2. Let the total number of students be x

   (4/9)x + 775 = x

   (4x/9) – x = -775

   x – (4x/9) = 775

   (5/9)x = 775

   x = 155×9 = 1395

   Total number of students = 1395

   So, the number of boys = 1395 – 775 = 620

   Hope it helps. Thank you.
