In a class of 60, where there are twice as many girls as boys, Kamal is ranked 17th from the top. There are 9 girls ahead of him in the ranking. How many boys are after him?

If there are 9 girls ahead of him , therre must be 7 boys ahead of him and then Kamal all of the rest of the boys are after him

now find how many boys are in class

b = boys 2b = girls

b + 2b = 60

b = 20

so there is 7 ahead + kamal = 8 in the top 17 which leaves 20 - 8 = 12 **after **Kamal
