Question

In a school 35% of students are girls and the number of boys are910 find the number of girls and total students

Answer 1

Let,

x be the total no.of students.

35%of total no. of students are girls

no. of girls=35/100*x

=7x/20

Then,

no.of boys= x-7x/20

=20x-7x/20= 13x/20........a

Given that,

no.of boys = 910...........b

from equations a and b,

13x/20=910

13x= 910*20

13x= 18200

x= 1400

therefore,

total no.of students =x=1400

no.of girls= 7x/20= 7*1400/20=490..
