Difficulty: Medium
Correct Answer: Cannot be determined
Explanation:
Introduction / Context:
The problem provides two chains that overlap only at Rakesh. We must find the shortest person, but some cross-comparisons are missing, leading to multiple consistent orders.
Given Data / Assumptions:
Concept / Approach:
Build allowable orders consistent with both chains. If the identity of the shortest varies across valid orders, the answer cannot be uniquely determined.
Step-by-Step Exploration:
Verification / Alternative check:
Try sample numeric heights consistent with the inequalities. You can realize both “Suresh shortest” and “Harish shortest” assignments without violating the statements.
Why Other Options Are Wrong:
Common Pitfalls:
Assuming unprovided comparisons (e.g., assuming Suresh < Harish) without justification.
Final Answer:
Cannot be determined
