Preeti ranked 9th from the bottom

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
