If INDIA is written as NIDAI in a certain code language, then CHINA will be written as _______.

Appeared in: JSSH Staff Nurse - 2019

Explanation

The coding pattern involves swapping pairs of letters within the word.
In the example 'INDIA', the first two letters (I, N) are swapped to become (N, I).
The middle letter (D) remains unchanged in its third position.
The last two letters (I, A) are also swapped to become (A, I).
This creates the code 'NIDAI' from 'INDIA'.
Applying this same pattern to 'CHINA', the first pair (C, H) becomes (H, C), the middle letter 'I' stays the same, and the last pair (N, A) becomes (A, N).

Option A: The code 'HCINA' correctly swaps the first pair of letters (C, H) but fails to swap the last pair (N, A). It keeps them in their original order.
Option B: The code 'CHIAN' correctly swaps the last pair of letters (N, A) but fails to swap the first pair (C, H), leaving them in their original order.
Option C: The code 'ANIHC' is the complete reverse of the word 'CHINA'. The established pattern from the example is a pair-wise swap, not a full reversal of the word.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Coding-Decoding by letter position swapping as background academic context rather than a clinical decision trigger.
While not a clinical question, this type of problem tests logical and analytical reasoning, which are crucial skills for nurses.
Pattern recognition helps in identifying trends in patient symptoms, vital signs, or lab results, which is essential for making sound clinical judgments and timely interventions.
Strong problem-solving skills enable nurses to adapt to unexpected situations and manage complex patient care scenarios effectively.

How to Approach the Question

First, carefully examine the relationship between the given word ('INDIA') and its code ('NIDAI').
Break down the transformation by comparing the position of each letter in the original and coded words.
Identify the specific rule or pattern. Here, the pattern is to swap the first and second letters, keep the third, and swap the fourth and fifth letters.
Apply this exact same rule to the new word ('CHINA').
Swap 'C' and 'H' to get 'HC'. Keep 'I'. Swap 'N' and 'A' to get 'AN'.
Combine the parts to form the final code ('HCIAN') and select the matching option from the list.
