BOYS are 7/11 part of students
so boys are 7/11 550 =350 Now no of girls is 550 - 350 =200
Step-by-step explanation:
let the number of boys and girls in school be 7x and 4x respectively.
so,7x+4x=550 (given)
so, 11x=550
x=50
therefore:total no of boys=7x =7 x 50 =350
total no of girls =4x=4 x 50 =200
