Tallest person from chained comparisons: Roshan is taller than Hardik, who is shorter than Sushil. Niza is taller than Harry but shorter than Hardik. Sushil is shorter than Roshan. Who is the tallest?

Introduction / Context:We are to deduce the tallest individual by chaining inequalities.

Given Data / Assumptions:

• Roshan > Hardik.
• Hardik < Sushil ⇒ Sushil > Hardik.
• Niza > Harry and Niza < Hardik ⇒ Hardik > Niza > Harry.
• Sushil < Roshan ⇒ Roshan > Sushil.

Concept / Approach:Combine to form a chain with Roshan at the top if both Roshan > Sushil and Sushil > Hardik are true.

Step-by-Step Solution:

Verification / Alternative check:No statement contradicts Roshan being above Sushil; rather it explicitly places Roshan above. Therefore, no one can exceed Roshan in the order.

Why Other Options Are Wrong:

• Sushil: Below Roshan.
• Hardik/Niza/Harry: Each is explicitly below someone else who is below Roshan.

Common Pitfalls:Reversing the direction of a comparison or overlooking the “Sushil is shorter than Roshan” constraint.

Final Answer:Roshan
