Question

The number of girls in a school is 340 less than the number of boys. If the total number of students in a school are 1040, find the number of girls in the school

Answer 1

heya mate
here is ur answer

(let the no. of boys be x and the no. of girls be x-340)

so, according to the question
total students =1040
=x+(x-340)=1040
=2x-340=1040
=2x=1040+340
=2x=1380
=x=1380/2
=x=690
=no. of boys=690
=no. of girls=690-340
=no. of girls=350

Answer 2

let the no of girls be x
no. of boys =340+x
total no. of student =1040
=1040-340=700
therefore - nuber of boys = 700
no.of girls =700-340=360
