If FISH = GJTI, how is BIRD coded?

Appeared in: Daman & Diu Staff Nurse - 2018

Explanation

The coding pattern is a simple forward shift in the alphabet.
Each letter in the word 'FISH' is shifted one position forward to get 'GJTI' (F+1=G, I+1=J, S+1=T, H+1=I).
Applying this +1 shift to 'BIRD' results in 'CJSE' (B+1=C, I+1=J, R+1=S, D+1=E).

Option B: The last letter 'F' is incorrect. It would result from a +2 shift from 'D' (D+2=F), which violates the consistent +1 shift pattern established by the example.
Option C: The third letter 'T' and the fourth letter 'F' are incorrect. 'T' would be a +2 shift from 'R', and 'F' would be a +2 shift from 'D'. The pattern must be consistent for all letters.
Option D: The last letter 'D' is incorrect. It is the same as the original letter, which represents a +0 shift, breaking the established +1 shift pattern.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Letter Substitution Cipher as background academic context rather than a clinical decision trigger.
This is a logical reasoning question, not a clinical one. It tests analytical and pattern-recognition skills.
These skills are foundational for problem-solving in any field, including interpreting data and recognizing patterns in patient symptoms or lab results in nursing.
What if? If the code for FISH was 'EHRG', the pattern would be a -1 shift (F-1=E, I-1=H, etc.). Applying this to 'BIRD' would result in 'AHQC'.

How to Approach the Question

First, analyze the relationship between the given pair of words (FISH and GJTI).
Determine the pattern by comparing the position of each letter in the first word to the corresponding letter in the second word.
Observe the shift: F is the 6th letter and G is the 7th (+1); I is the 9th and J is the 10th (+1); S is the 19th and T is the 20th (+1); H is the 8th and I is the 9th (+1).
Identify the consistent pattern, which is a '+1' shift for every letter.
Apply this same +1 shift pattern to the target word 'BIRD' to find the coded word.
Compare your result with the given options to select the correct answer.
