If 'green' is called 'white', 'white' is called 'yellow', 'yellow' is called 'blue', 'blue' is called 'pink' and 'pink' is called 'black', then what is the colour of sky?

1. A

   green

2. B

   blue

3. C

   pink

4. D

   yellow

Appeared in: PGIMER Chandigarh NO - 2015

Explanation

• The question establishes a simple substitution code for a set of colors.
• The first step is to identify the actual color of the object in question, which is the sky. The sky is blue.
• The next step is to find the code for 'blue' in the given list. The problem states, "'blue' is called 'pink'".
• By applying this rule, the correct answer is determined to be 'pink'.

Why Other Options Were Wrong

• Option A: The sky is not naturally green. According to the code, 'green' is called 'white'.
• Option B: This is the actual color of the sky, but the question requires the answer to be in the provided code, not the real-world color.
• Option D: The sky is not naturally yellow. According to the code, 'yellow' is called 'blue'.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical reasoning, specifically the skill of coding and decoding by substitution as background academic context rather than a clinical decision trigger.
• This is a general intelligence question, not a clinical one. However, logical reasoning is a crucial skill for nurses.
• Nurses use deductive and inductive reasoning daily to assess patient conditions, interpret data, and make critical decisions.
• For example, if a patient's monitor shows a specific arrhythmia pattern (Fact A), and the nurse knows this pattern is associated with a particular electrolyte imbalance (Rule B), they can deduce the potential problem (Conclusion C).

How to Approach the Question

• First, carefully read the question to understand the coding system. Note down each color and its corresponding code word.
• Identify the object the question is asking about: 'the sky'.
• Determine the actual, real-world color of that object. The sky is blue.
• Look for the rule in the coding system that applies to the color 'blue'.
• The problem states, "'blue' is called 'pink'".
• Select the option that corresponds to this coded word. In this case, it is 'pink'.
