Question

in aco educational school, ,45%of the total are girls. If there are 440 boys in the school, find the number of girls in the school

Answer 1

percent of boys =100-45
=55 percent
let total no. of students be y
therefore,
55percent of y =440
55/100x y=440
y=800
no. of girls= 45/100x800
=360

Answer 2

solution :
no. of boys=440
no. of girls percent =45%
now,
let the total no. of students in an aco educational school be 'x'
according to the question,
100%-45%=55% I. e. percent of boys
again,
55%ofx=440
55/100*x=440
x=800
similarly,
no. of girls= 45%of x
=45/100*800
=360
