Question

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

Options

• 3

• 7

• 12

• 23

Answer 1

12
Explanation:
Number of boys = 20
Number of girls = 40
Number of students behind Kamal in rank = (60 - 17) = 43
Number of girls ahead of Kamal in rank = 9
Number of girls behind Kamal in rank = (40 - 9) = 31
Number of boys behind Kamal in rank = (43 - 31) = 12
