If TRUST should be coded as RPSQR, then HONEST will be coded as ______?

Appeared in: ESIC Nursing Officer 2016 (Shift -2)

Explanation

The coding logic is a consistent backward shift of 2 positions in the English alphabet for every letter.
In the example 'TRUST' becomes 'RPSQR', each letter is replaced by the letter two places before it (T-2=R, R-2=P, U-2=S, S-2=Q, T-2=R).
Applying this '-2' rule to 'HONEST' gives 'FMLCQR' (H-2=F, O-2=M, N-2=L, E-2=C, S-2=Q, T-2=R).

Option B: This option is an anagram (a jumbled version) of the letters in the original word 'HONEST', not a coded transformation based on the established pattern.
Option C: This option incorrectly codes some of the letters. While 'F' and 'M' are correct for 'H' and 'O', the letters 'C', 'R', 'Q', 'L' do not follow the '-2' shift rule for 'N', 'E', 'S', and 'T'.
Option D: This option presents an incorrect sequence of letters that does not correspond to the '-2' shift pattern. For example, 'R' is not 'O-2', and 'C' is not 'S-2'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Coding-Decoding by Letter Shifting as background academic context rather than a clinical decision trigger.
While not a clinical question, logical reasoning is a crucial skill for nurses.
It enables quick and accurate decision-making, such as interpreting patient data, prioritizing care, and troubleshooting medical equipment under pressure.
Strong reasoning skills help in identifying subtle changes in a patient's condition and responding appropriately.

How to Approach the Question

First, carefully examine the relationship between the letters of the given word ('TRUST') and its corresponding code ('RPSQR').
Assign numerical positions to the letters to identify a mathematical pattern (e.g., A=1, B=2, ...).
In this case, T(20) -> R(18), R(18) -> P(16), revealing a consistent '-2' shift.
Confirm this pattern for all letters in the example word.
Apply the identified rule ('-2' shift) to each letter of the word you need to code ('HONEST').
Construct the resulting code ('FMLCQR') and select the matching option.
