In a certain code, CAT is written as SATC and DEAR is written as QEARD. How would SING be written in that code?

Appeared in: AIIMS Raipur NO- 2019 (shift 3rd)

Explanation

The coding pattern involves moving the first letter to the end and replacing it with the letter preceding the original word's last letter.
For 'CAT', 'C' moves to the end, and 'S' (before 'T') becomes the first letter, resulting in 'SATC'.
For 'DEAR', 'D' moves to the end, and 'Q' (before 'R') becomes the first letter, resulting in 'QEARD'.
Applying this to 'SING', 'S' moves to the end, and 'F' (before 'G') becomes the first letter, creating the code 'FINGS'.
Since 'FINGS' is not available in the options, 'None of these' is the correct answer.

Option A: The option 'GNISS' does not follow the established pattern. It seems to involve reversing the word and shifting letters, which is inconsistent with the logic derived from the examples.
Option C: The option 'SGNIS' incorrectly places 'S' at the beginning and reverses 'ING'. This does not match the consistent pattern of letter movement and substitution seen in the examples.
Option D: The option 'BGINS' does not align with the coding logic. The first letter 'B' has no logical connection to the last letter 'G' of 'SING' based on the established rule (G-1 = F, not B).

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 as background academic context rather than a clinical decision trigger.
This question is not clinically relevant as it tests logical reasoning, a general aptitude skill.
Strong logical reasoning and pattern recognition are crucial for nurses in clinical practice for tasks like interpreting diagnostic data, identifying trends in a patient's condition, and troubleshooting equipment.
For example, a nurse needs to recognize the pattern of deteriorating vital signs to escalate care appropriately.

How to Approach the Question

First, carefully analyze the given examples (CAT -> SATC, DEAR -> QEARD) to find a consistent rule.
Break down the transformation. Notice how the letters in the original word are rearranged or substituted to form the code.
Formulate a hypothesis for the rule. Here, the rule is: move the first letter to the end, and the new first letter is the one preceding the original last letter.
Test your hypothesis on all given examples to ensure it holds true.
Once the rule is confirmed, apply it to the word in the question ('SING').
Compare your result ('FINGS') with the given options. If it matches one, that's the answer. If not, select 'None of these'.
