It WARNER is coded for iduphu, then cooler will be coded as______:

Appeared in: ESIC Nursing Officer 2016 (shift-1)

Explanation

The logical pattern is a consistent forward shift of each letter in the word by three positions in the alphabet.
The example pair 'WARNER' and 'iduphu' contains a likely typo. The code 'iduphu' correctly corresponds to the word 'FARMER' with a +3 shift (F+3=I, A+3=D, R+3=U, M+3=P, E+3=H, R+3=U).
Applying this +3 shift pattern to the word 'COOLER' gives: C+3=F, O+3=R, O+3=R, L+3=O, E+3=H, R+3=U.
The final coded word is FRROHU.

Option A: This option has an incorrect last letter. Applying a +3 shift to 'R' results in 'U', not 'H'.
Option B: This option has an incorrect third letter. Applying a +3 shift to the second 'O' in COOLER results in 'R', not 'O'.
Option C: This option has incorrect letters in the second and fourth positions. The code for 'O' is 'R' (not 'O'), and the code for 'L' is 'O' (not 'R').

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 does not test clinical nursing knowledge but assesses general intelligence and logical reasoning.
Problem-solving and analytical skills are crucial for nurses in clinical settings to make quick and accurate decisions.
What if the pattern was a -2 shift? If the pattern was subtracting 2 letters, 'COOLER' would be coded as 'AMMJCP'.

How to Approach the Question

First, carefully examine the relationship between the given word (WARNER) and its code (iduphu).
Try to identify a consistent pattern, such as a fixed number of letters being added or subtracted (alphabetical shift).
If the pattern is not consistent (as with 'WARNER'), consider the possibility of a typo in the question's example. Test a similar word ('FARMER') to see if it creates a consistent pattern (+3 shift).
Once the correct logical rule (+3 shift) is confirmed, apply it systematically to each letter of the target word ('COOLER').
Construct the new code letter by letter (C+3=F, O+3=R, etc.).
Finally, compare your resulting code with the given options to identify the correct answer.
