In a certain code language, AUTHOR is written as YDDOGC. How will WRITER be written in the same language?

Appeared in: UP NHM CHO 7 Sept 2022(shift-1st)

Explanation

The coding pattern involves finding the opposite letter for each character in the word.
A sequentially increasing number (starting from 1) is then subtracted from the alphabetical position of the opposite letter.
For 'W', the opposite is 'D' (4). Subtracting 1 gives 3, which is 'C'.
For 'R', the opposite is 'I' (9). Subtracting 2 gives 7, which is 'G'.
Following this pattern for all letters in 'WRITER' yields 'CGOCQC'.

Option A: This option, CQCGCO, incorrectly codes the third letter. The third letter 'I' has 'R' (18) as its opposite. Subtracting 3 gives 15 ('O'), not 'G'.
Option B: This option, CQCGOC, incorrectly codes the last three letters. It seems to swap the positions of 'O' and 'C' and incorrectly codes the fifth letter 'E' as 'O' instead of 'Q'.
Option D: This option, COGCQC, incorrectly codes the second letter. The second letter 'R' has 'I' (9) as its opposite. Subtracting 2 gives 7 ('G'), not 15 ('O').

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Coding-Decoding as background academic context rather than a clinical decision trigger.
This is a logical reasoning question designed to test pattern recognition and analytical skills, which are essential for problem-solving in any field.
While not directly clinical, the ability to decode complex patterns is analogous to a nurse's need to interpret complex patient symptoms, lab results, and monitoring data to identify underlying health issues.
What if the subtraction was a fixed number instead of sequential? If the rule was 'Opposite Position - 3' for every letter, the code for AUTHOR would be WCFSLF, and the entire problem-solving approach would need to be adjusted.

How to Approach the Question

First, carefully analyze the relationship between the given word ('AUTHOR') and its code ('YDDOGC'). Look for simple patterns like letter shifts or reversals.
If simple patterns don't work, consider more complex rules, such as using opposite letters or mathematical operations based on letter positions.
Write down the alphabet and their corresponding positions (A=1, B=2, ...) to help with calculations.
Test your hypothesis. In this case, the pattern is (Position of Opposite Letter) - (Letter's index in the word). Verify this rule for every letter in 'AUTHOR'.
Once the pattern is confirmed, apply the exact same rule to the target word ('WRITER') step-by-step.
Compare your resulting code with the given options to find the correct match.
