Question

a school has 200 students. one third of the boys have blue eyes and one quarter of the girls have blue eyes. given that a total of 57 students have blue eyes how many boys attend the school

Answer 1

Answer:

let number of boys attend the school be X

hence number of girls attend the school =200-X

Number of boys with blue eyes = 1/3×X

= X/3

Number of girls with blue eyes

= 1/4×(200-X)

= 200-X/4

ATC

(X/3) + (200-X/4) = 57

(4X+600-3X/12) = 57

(X+600/12) = 57

(X+600) = 57×12

X = 684 - 600

X = 84

hence number of boys attend the school

= X = 84
