Question

A class has 4 more girls than boys. On a day when only 8 boys were absent, the number of girls was twice that of the boys. How many girls and boys are there in the class?​

Answer 1

Answer:

Let the number of boys be x

number of girls x+4

when 8 boys were absent, the number of boys x-4

when 8 boys were absent

number of girls= 2x(no of boys)

x+4=2(x-8)

x+4=2x-16

2x-16=x+4

x=20

No of boys= 20

No of girls = 20+4= 24.

Answer 2

$\huge\boxed{Answer}$

Let the number of boys be x

no of girls = x+4

no of boys when all are present x+8

no of girls = 2*(x+8)= 2x+16

total students = 2x+x+16+8= 3x+24
