Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the one that is different.

Appeared in: DSSSB 13 August 2024

Explanation

The core logic is based on the classification of English alphabet letters into vowels and consonants.
AER is the correct answer because it is the only letter cluster among the options that contains vowels (A and E).
The other three options consist exclusively of consonants, establishing a clear pattern that AER breaks.

Option A: DHW consists entirely of consonants (D, H, W). It follows the common pattern shared by two other options.
Option B: PTK is composed only of consonants (P, T, K). It fits the majority pattern.
Option C: TXG contains only consonants (T, X, G). It adheres to the common pattern and is therefore not the different one.

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 (Letter Classification) as background academic context rather than a clinical decision trigger.
This type of question tests logical and analytical reasoning, a critical skill for nurses in clinical problem-solving and decision-making.
Quickly identifying patterns and anomalies is analogous to a nurse spotting an unusual symptom or a deviation in a patient's vital signs from the expected pattern.
What if the options were 'ACE', 'DFH', 'IKM', 'PRT'? The pattern would shift from vowel/consonant to alphabetical sequence. All options show letters with a gap of one letter in between (A-C-E, D-F-H, etc.). A different type of outlier would need to be introduced to make the question solvable.

How to Approach the Question

First, carefully read the question to understand the task, which is to find the 'different' or 'odd' one out from a set of four options.
Examine each letter cluster individually.
Look for a common property or pattern shared by three of the clusters. Start with the simplest properties.
Check for the presence of vowels vs. consonants. This is often a primary differentiator.
If that doesn't work, consider other patterns like alphabetical order, the number of letters between each character, or the sum of their positional values.
The cluster that does not fit the identified common pattern is the correct answer.
