Two-end ranks in one class: Sohan is 7th from the top and 26th from the bottom. How many students are in the class?

Introduction / Context:When both top-rank and bottom-rank of the same student are known in a single line, total strength is computed by adding the two and subtracting 1 (as the student is counted twice otherwise).

Given Data / Assumptions:

• Sohan's top-rank = 7.
• Sohan's bottom-rank = 26.

Concept / Approach:Total N = top-rank + bottom-rank − 1.

Step-by-Step Solution:

Verification / Alternative check:7 above Sohan and 25 below him sum to 32 when including Sohan.

Why Other Options Are Wrong:

• 31, 33, 34: Off by ±1 or ±2 due to missing the minus 1.
• None of these: Correct option exists.

Common Pitfalls:Forgetting to subtract 1 when combining the two ranks.

Final Answer:32
