Calculating Class Composition
We start by determining the total number of girls and boys in the class.
The total number of students is given as 88.
The number of girls is stated to be 5/8 of the total students. We can calculate this as:
Number of girls = \( \frac{5}{8} \times 88 \)
Number of girls = \( 5 \times 11 \)
Number of girls = 55
Now, we can find the number of boys by subtracting the number of girls from the total number of students:
Number of boys = Total students - Number of girls
Number of boys = \( 88 - 55 \)
Number of boys = 33
Analyzing Rahul's Position
Next, we analyze Rahul's rank and the students positioned before him.
Rahul is the 16th student from the top. This means there are \( 16 - 1 = 15 \) students ahead of him in the ranking.
We are told that there are 12 girls ahead of Rahul among these 15 students.
To find the number of boys ahead of Rahul, we subtract the number of girls ahead from the total students ahead:
Boys ahead of Rahul = Total students ahead - Girls ahead of Rahul
Boys ahead of Rahul = \( 15 - 12 \)
Boys ahead of Rahul = 3
Since there are only 3 boys ahead of Rahul, and he is ranked 16th, Rahul himself must be a boy.
Determining Boys After Rahul
Finally, we calculate the number of boys who are ranked after Rahul.
We know the total number of boys in the class is 33.
We also know that there are 3 boys ahead of Rahul, and Rahul himself is a boy. So, the total number of boys up to and including Rahul's position is:
Boys up to and including Rahul = Boys ahead of Rahul + 1 (Rahul)
Boys up to and including Rahul = \( 3 + 1 \)
Boys up to and including Rahul = 4
To find the number of boys after Rahul, we subtract the number of boys up to and including his position from the total number of boys in the class:
Number of boys after Rahul = Total number of boys - Boys up to and including Rahul
Number of boys after Rahul = \( 33 - 4 \)
Number of boys after Rahul = 29
