Answer
Correct Answer: Deepti
Explanation
Introduction / Context:This is a classic ranking/ordering puzzle involving relative ages. We must translate comparative statements into an ordered chain and identify the oldest (maximum) element.
Given Data / Assumptions:
- Sohan is Seema's younger brother ⇒ Sohan is younger than Seema.
- Sohan is older than Seeta ⇒ Sohan > Seeta.
- Sweta is younger than Deepti but older than Seema ⇒ Deepti > Sweta > Seema.
- All people are distinct individuals; ages are comparable (no ties stated).
Concept / Approach:Convert each comparison into a chain and then merge the chains carefully. The symbol “>” means “older than.”
Step-by-Step Solution:
From “younger brother”: Seema > Sohan.Given Sohan > Seeta ⇒ Seema > Sohan > Seeta.From “Sweta younger than Deepti but older than Seema”: Deepti > Sweta > Seema.Merge: Deepti > Sweta > Seema > Sohan > Seeta.Verification / Alternative check:Every statement is satisfied by the merged chain: Sohan younger than Seema, yet older than Seeta; Sweta between Deepti and Seema; Deepti above all those three. No conflicts appear.
Why Other Options Are Wrong:Seema is below Sweta; Sweta is below Deepti; Seeta is second youngest. Hence none of them is the eldest.
Common Pitfalls:Forgetting “younger brother” implies strict order, not equality; or reversing “older than/younger than.”
Final Answer:Deepti
