In a class of 60, where girls are twice that of boys, Kamal ranked seventeenth from the top. If there are 9 girls ahead of Kamal, how many boys are after him in rank ?

One Answer on this Question

1. boys= x
   girls=2x
   boys+girls= 60
   x+2x=60
   x=60/3
   x=20
   kamal=17th rank
   9 girls are ahead of kamal
   17-9=8
   20-8=12 boys are after kamal’s rank
