Question

2. 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:

No.of girls is 24

No. of boys is 20

Step-by-step explanation:

Let no. of boys in the class be x,∴ no. of girls =x+4

When no. of boys present in a class = x−8 then no. of girls =2×no. of boys=2(x−8)

No. of girls =x+4=2(x−8)⇒2x−x=16+4⇒x=20

No. of boys =x=20

No. of girls =x+4=20+4=24
