The ratio of boys to girls in a certain classroom was 2 : 3. If boys represented five more than one third of the class, how many people were there in the classroom?
Let the no. Of boys=x and that of girls=y. The total no. Of students = x+y . As given by statement the no. Of boys=x={(x+y)/3} + 5 This implies that X=(x+y+15)/3 Also we know that x/y = 2/3 therefore From this equation we get x=2y/3 and y=3x/2 By method of substitution we get X=(x+3x/2+15)/3 •x=(15x+90)/2 •2x=15x+90 •-13x=90 X= -90/13 Now. Y= 3x/2=-270/26 Therefore total no. Of students= -270/26+(-90/13) •no. Of students= -450/26 According to me this is an imaginary question i mean how can their be a negative person
