Question

In a class the number of boys is 5 more than the number of girls.If their ratio is 6:5 find the number of girls in the class.Also,write the total number of students

Answer 1

let no. of girls be x, boys = x+5.
(x+5)/x=6/5
5x+25=6x
25=6x-5x
25=x
girls = 25,boys =25+5=30
total no =25+30=55

Answer 2

Let x be the total no: of students
6+5=11
6/11x=5/11x+5
6/11-5/11=5
6-5=1/11
11x=5
x=5/11
