In a certain code language, if ADOPT is coded as GDRWS, then how is DATED coded in that language?

Appeared in: RRB Nsg. Superintendent-20 July 2019 (Shift-2)

Explanation

The correct coding follows a two-step logic derived from the example 'ADOPT' -> 'GDRWS'.
Step 1: The first and last pairs of letters are swapped. For 'DATED', 'DA' becomes 'AD' and 'ED' becomes 'DE', forming the intermediate word 'ADTDE'.
Step 2: Each letter of the intermediate word is shifted forward by 3 positions in the alphabet.
'A' (+3) -> 'D'.
'D' (+3) -> 'G'.
'T' (+3) -> 'W'.

Option A: This option does not follow the established two-step pattern of reversing pairs and shifting by +3.
Option B: This option is incorrect as it does not match the result from applying the identified logic. The letters and their positions are inconsistent with the pattern.
Option C: This option results from applying the two steps in the wrong order. If you first shift 'DATED' by +3, you get 'GDWGH', and then reversing the pairs would lead to a different, incorrect answer.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain This question tests logical reasoning skills, specifically in the area of coding and decoding by letter manipulation as background academic context rather than a clinical decision trigger.
This is a general intelligence question, not a clinical one.
Logical reasoning and pattern recognition are crucial skills for nurses in clinical practice.
These skills help in interpreting patient data, recognizing trends in vital signs, and making sound clinical judgments under pressure.

How to Approach the Question

First, carefully examine the given example: the word 'ADOPT' and its code 'GDRWS'.
Analyze the relationship between the letters of the word and the code. Look for simple patterns like a uniform forward or backward shift for all letters.
If a simple pattern doesn't fit, test for more complex rules. Check for reversal of the word, swapping of letter pairs, or position-based shifts.
In this case, identify the two-step pattern: 1) Swap the first and last pairs of letters. 2) Shift every letter of the new word forward by 3 places.
Verify this pattern with the given example ('ADOPT' -> 'DAOTP' -> 'GDRWS').
Once the pattern is confirmed, apply the exact same steps to the target word 'DATED'.
