Find the tallest using chained height comparisons: Umesh is taller than Satish. Suresh is shorter than Neeraj but taller than Umesh. Who is the tallest among Umesh, Satish, Suresh, and Neeraj?

Introduction / Context:
A short chain of inequalities can still identify an extreme (tallest). Here, we link the given comparisons and see who must be at the top.

Given Data / Assumptions:

• Umesh > Satish.
• Suresh > Umesh.
• Neeraj > Suresh.
• All heights are distinct.

Concept / Approach:
Transitivity of “taller than” gives a strict chain ending with Neeraj above Suresh, who is above Umesh, who is above Satish.

Step-by-Step Solution:

Verification / Alternative check:
Assign example heights (e.g., Neeraj 185, Suresh 180, Umesh 175, Satish 170). All constraints hold and Neeraj is tallest.

Why Other Options Are Wrong:

• Suresh/Umesh/Satish are each below someone else in the chain.

Common Pitfalls:
Reversing any “shorter than” statement or overlooking the strictness of comparisons.

Final Answer:
Neeraj
