If MEN is coded as MIN and WOMAN as WUMIN, then CHILD will be coded as

Appeared in: RRB Staff Nurse Jaipur-6th June 2018

Explanation

The coding pattern involves keeping the consonants unchanged while modifying the vowels.
Each vowel in the original word is replaced by the next vowel in the standard alphabetical sequence: A, E, I, O, U.
In the word 'CHILD', the only vowel is 'I'.
Following the rule, 'I' is replaced by the next vowel, which is 'O'.
The consonants C, H, L, and D remain in their positions, resulting in the coded word 'CHOLD'.

Option B: This option replaces 'I' with 'U'. In the vowel sequence (A, E, I, O, U), 'U' is two positions after 'I', which violates the 'next vowel' rule.
Option C: This option replaces 'I' with 'E'. 'E' comes before 'I' in the vowel sequence. The established pattern is a forward progression.
Option D: This option replaces 'I' with 'A'. 'A' is two positions before 'I' in the vowel sequence and does not fit the forward progression rule.

Visual 1: Flowchart - A flowchart illustrating the coding logic. It would start with the word 'CHILD', branch to identify consonants (C,H,L,D) and vowels (I). The vowel 'I' path would show the vowel sequence A-E-I-O-U, highlighting the shift from 'I' to 'O'. Finally, it would recombine the letters to form 'CHOLD'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Coding and Decoding as background academic context rather than a clinical decision trigger.
This type of question assesses logical and deductive reasoning, which are fundamental cognitive skills.
While not directly clinical, strong problem-solving abilities are essential for nurses to analyze patient data, identify patterns in symptoms, and make sound clinical judgments quickly and accurately.
What if the rule was to replace each letter with the next letter in the alphabet? Then CHILD would become DIJME.

How to Approach the Question

First, analyze the relationship between the given word-pair: MEN and MIN.
Observe which letters remain constant (M, N) and which one changes (E -> I).
Formulate a hypothesis for the rule. The change is between two vowels. List the vowels: A, E, I, O, U. Notice that 'I' is the immediate next vowel after 'E'.
The hypothesized rule is: Consonants do not change; vowels are replaced by the next vowel in the sequence.
Apply this rule to the word CHILD. Identify the consonants (C, H, L, D) and the vowel (I).
According to the rule, replace 'I' with the next vowel, 'O'.
