Which of the following Venn diagrams best represents the relationship between apples, mangoes and vegetables?

Appeared in: DSSSB - 28 August 2019 (Shift-1)

Explanation

Apples and Mangoes are both classified as fruits, but they are distinct types of fruit. An apple cannot be a mango, so their sets are separate.
Vegetables form a completely separate food group from fruits. An apple or a mango is not a vegetable.
Therefore, there is no overlap or commonality between the three categories: Apples, Mangoes, and Vegetables.
In a Venn diagram, sets with no common elements are represented as separate, non-intersecting (disjoint) circles.

Option B: This diagram shows two intersecting circles inside a larger one. This would represent two overlapping sub-categories within a larger universal set, which does not fit the relationship between apples, mangoes, and vegetables.
Option C: This diagram shows three mutually intersecting circles. This implies that all three categories share some common elements, which is false. An apple is not a mango or a vegetable.
Option D: This diagram shows two separate circles inside a larger one. This implies that two distinct sub-categories belong to one larger universal set. It is incorrect here because vegetables are not a superset of apples and mangoes.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Venn Diagrams as background academic context rather than a clinical decision trigger.
This question tests logical reasoning, a critical skill for nurses for problem-solving and decision-making in clinical settings.
While not directly clinical, the ability to categorize information is fundamental to nursing processes like triage, differential diagnosis, and care planning.
What if the question was 'Fruits, Apples, Vegetables'? The diagram would show one circle (Apples) inside a larger circle (Fruits), with a third separate circle for Vegetables.

How to Approach the Question

Step 1: Identify the three categories given in the question: Apples, Mangoes, and Vegetables.
Step 2: Analyze the relationship between each pair of categories.
Step 3: Ask: Is an apple a mango? No. Their circles must be separate.
Step 4: Ask: Is an apple or a mango a vegetable? No. The fruit circles must be separate from the vegetable circle.
Step 5: Conclude that all three categories are mutually exclusive (disjoint), meaning they have no elements in common.
Step 6: Select the Venn diagram that shows three separate, non-intersecting circles.
