Difficulty: Medium
Correct Answer: Cannot be determined
Explanation:
Introduction / Context:
Height-ranking questions require building partial order chains. Sometimes the data are sufficient to determine extremes; other times, uncertainty remains. Recognizing insufficiency is a key reasoning skill.
Given Data / Assumptions:
Concept / Approach:
Construct a chain that is consistent: Amar > Rakesh > Mukesh > Suresh and Rakesh > Harish. The unknown link is between Suresh and Harish; either could be shorter.
Step-by-Step Solution:
Verification / Alternative check:
Try two consistent placements: (a) Harish taller than Suresh ⇒ Suresh shortest; (b) Suresh taller than Harish ⇒ Harish shortest. Both satisfy the given constraints, proving non-uniqueness.
Why Other Options Are Wrong:
Common Pitfalls:
Forcing a total order when only partial comparisons are given. Always check if multiple arrangements fit.
Final Answer:
Cannot be determined
