If in a certain code language AC means 'Party is amazing', DEC means 'amazing and fun', DF means 'fun loving', then what is the code for 'and'?

Appeared in: DSSSB - 29 August 2019 (Shift-1)

Explanation

The problem requires decoding a simple substitution cipher by comparing phrases.
By comparing 'DEC' ('amazing and fun') and 'DF' ('fun loving'), the common word 'fun' is matched with the common code 'D'.
Next, comparing 'AC' ('Party is amazing') and 'DEC' ('amazing and fun'), the common word 'amazing' is matched with the common code 'C'.
In the phrase 'DEC' ('amazing and fun'), since 'D' is 'fun' and 'C' is 'amazing', the remaining code 'E' must correspond to the remaining word 'and'.

Option B: The code 'D' is incorrect because it represents the word 'fun', as identified by comparing the phrases 'amazing and fun' (DEC) and 'fun loving' (DF).
Option C: The code 'B' is incorrect because it does not appear in any of the given coded phrases (AC, DEC, DF). Therefore, it cannot represent any of the words in those phrases.
Option D: The code 'C' is incorrect because it represents the word 'amazing', as identified by comparing the phrases 'Party is amazing' (AC) and 'amazing and fun' (DEC).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Coding-Decoding by Comparison as background academic context rather than a clinical decision trigger.
This is a logical reasoning question, not a clinical one. It is included in nursing exams to assess general intelligence and problem-solving skills, which are essential for critical thinking in clinical practice.
What if? - If the stem changed one defining clue so that E no longer matched, reassess the option whose mechanism, classification, or indication now fits the revised presentation.

How to Approach the Question

First, identify the phrases and their corresponding codes provided in the question.
Look for pairs of coded phrases that share a common word.
Identify the common code letter between these two phrases. This letter is the code for the common word.
Repeat this process to decode as many words as possible.
Use the process of elimination on a single phrase once you have decoded some of its words to find the code for the remaining word.
Select the option that matches your final decoded word.
