Detailed Solution & Logic
16
Step 1: Understand the problem
-
Let the total number of students in the class be N.
-
Preeti's rank from the top = 8
-
Preeti's rank from the bottom = 9
Step 2: Use the formula for total students
There is a simple formula:
Total students=Rank from top+Rank from bottom−1
This works because the same student is counted in both ranks, so we subtract 1 to avoid double counting.
Step 3: Substitute the values
N=8+9−1
N=16
✅ Step 4: Answer
Total number of students in the class = 16
