Question

in a co- educational school, 45℅ of the total students are girls. if there are 440 boys in the school ,find the number of girls in the school

Answer 1

Let the total no of students be x
No of girls =45/100*x=9x/20
No . Of boys =x-9x/20
A/Q
X-9x/20=440
20x-9x/20=440
11x/20=440
x=440*20/11
X=800
Now total no of student =800
Then total no. of girls =800*45/100
=360
Check
No.girls+no.of boys =800
No.of girls=800-440
=360

45% of girls=45×8

=360
