Question

in a class of 50 students,the number of girls is 3/5ofthe number of boys. find the number of girls in class

Answer 1

The number of students =50
The number of the girls = 3/5*50
The number of girls =30

Answer 2

let the boys are x
so the girls are 3x/5
so x+3x/5=50
or 5x+3x=50*5=250
or 8x=250
or x=250/8=31
so the no of boys = 31 & no of girls=40-31=9
