Height ordering with partial comparisons: Mukesh is taller than Suresh but shorter than Rakesh. Rakesh is taller than Harish but shorter than Amar. Who is the shortest?

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:

• Mukesh > Suresh.
• Mukesh < Rakesh.
• Rakesh > Harish.
• Rakesh < Amar.
• No direct comparison between Suresh and Harish, or between Amar and others except via Rakesh.

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:

• Picking Mukesh/Harish/Suresh outright assumes an ordering not supported by data.

Common Pitfalls:Forcing a total order when only partial comparisons are given. Always check if multiple arrangements fit.

Final Answer:Cannot be determined
