Find out odd one in the following?

Appeared in: Combined AIIMS - 2020 (Jodhpur, Bhopal, Patna, Raipur)

Explanation

Nagpur is the correct answer because it is the only city in the list that is not a primary state capital.
Mumbai is the capital of Maharashtra, Kolkata is the capital of West Bengal, and Chennai is the capital of Tamil Nadu.
Nagpur serves as the winter capital of Maharashtra, but the primary capital is Mumbai.
Additionally, Nagpur is a landlocked city, whereas Mumbai, Kolkata, and Chennai are all coastal or port cities.

Option A: Mumbai is a primary state capital (Maharashtra) and a coastal city, fitting the pattern established by the other distractors.
Option B: Kolkata is a primary state capital (West Bengal) and a major port city, which is consistent with the characteristics of Mumbai and Chennai.
Option D: Chennai is a primary state capital (Tamil Nadu) and a coastal city, matching the properties of Mumbai and Kolkata.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Odd One Out (Indian Cities) as background academic context rather than a clinical decision trigger.
While not a clinical question, general knowledge is important for healthcare professionals for better communication and building rapport with patients from diverse backgrounds.
Understanding the geography and administration of the country helps in comprehending patient demographics, travel history, and potential exposure to regional health issues.
What if? - If the option was 'Bhopal' instead of 'Nagpur', the logic would be the same as Bhopal is a state capital (Madhya Pradesh) but landlocked. The question would then have two possible answers based on two different logics (capital status vs. location), making it ambiguous.

How to Approach the Question

First, analyze the given options: Mumbai, Kolkata, Nagpur, and Chennai. Recognize that these are all major Indian cities.
Look for a common property or relationship shared by most of the options. Consider different categories for comparison, such as geographical location (coastal vs. landlocked) and administrative status (capital city vs. other major city).
Evaluate each option against these categories. You will notice that Mumbai, Kolkata, and Chennai are all primary state capitals and are located on or near the coast.
Identify the option that does not share these common properties. Nagpur is not a primary state capital (it's a winter capital) and it is landlocked.
Conclude that Nagpur is the 'odd one out' because it differs from the other three on at least two significant criteria.
