Solution

To solve this problem, we need to follow these steps:

  1. We know that girls are twice the number of boys in the class. Let's denote the number of boys as 'b'. Then the number of girls would be '2b'. The total number of students in the class is 72. So, we can write the equation as: b + 2b = 72. Solving this equation, we get b = 24. So, there are 24 boys and 48 girls in the class.

  2. Ravi's rank is 24th from the top. This means there are 23 students above him.

  3. Out of these 23 students, 13 are girls. So, the remaining 10 students are boys.

  4. Since there are 24 boys in total and 10 are above Ravi, there must be 24 - 10 = 14 boys below Ravi.

So, the correct answer is 14.
