Seema's younger brother Sohan is older than Seeta. Sweta in younger than Deepti but elder than Seema, who is the eldest?

Appeared in: NHM UP Staff Nurse-2021 Shift-2nd

Explanation

The question requires establishing a chronological order of age based on relative comparisons.
The statement "Sweta is younger than Deepti but elder than Seema" places both Sweta and Seema as younger than Deepti.
Combining this with the first statement (Seema > Sohan > Seeta) confirms that Deepti is at the top of the age hierarchy.
The final derived order is Deepti > Sweta > Seema > Sohan > Seeta, which clearly identifies Deepti as the eldest.

Option A: Seema cannot be the eldest because the second statement explicitly says that Sweta is elder than Seema.
Option B: Sweta cannot be the eldest because the second statement explicitly says that Sweta is younger than Deepti.
Option C: Seeta is the youngest or one of the youngest. The first statement establishes that Sohan is older than her, and Seema is older than Sohan.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Ordering and Ranking as background academic context rather than a clinical decision trigger.
This question tests logical and analytical reasoning, a critical skill for nurses.
Nurses use logical deduction daily for prioritizing patient care, interpreting diagnostic data, and making sound clinical judgments under pressure.
What if the second statement was 'Sweta is elder than Deepti'? In that case, Sweta would be the eldest, as the order would become Sweta > Deepti and Sweta > Seema.

How to Approach the Question

First, carefully read all the statements provided in the question.
Break down each statement into simple comparisons. Use symbols like '>' for 'older than' and '<' for 'younger than' to represent the relationships.
Translate phrases like 'A is younger than B but older than C' into two separate comparisons (B > A and A > C).
Combine all the individual comparisons into a single, continuous sequence or chain.
Once the final order is established, identify the person at the beginning of the sequence (for eldest) or at the end (for youngest) to answer the question.
