Answer» Correct Answer - Option 1 : 12

According to the given information:

Total students = 60

Let the number of girls be = x

Then, the number of boys = 2x

Now,

x + 2x = 60

3x = 60

x = 60 / 3

x = 20

Given, Reena's rank from the top = 17th

Number of boys in front of Reena = 9

Number of girls in front of Reena = 17 - 1 - 9 = 7

Thus, the number of girls after Reena = 20 - 7 - 1 = 12

Hence, the correct answer is "12".
