Mixed transform – ROT13 with a minor positional swap pattern PSQR : CFED :: JMKL : ?
Correct Answer: WZYX
Introduction / Context:This analogy involves a fixed 13-position rotation (ROT13) combined with a slight reordering. Such composite patterns are common in reasoning tests to check attention to detail.
Given Data / Assumptions:
- PSQR maps to CFED.
- We use alphabet indices A=1 … Z=26 and consider ROT13: each letter L becomes L+13 with wrap-around.
- We look for any ordering adjustment after rotating.
Concept / Approach:First, apply ROT13 to the source letters. Then compare the direct ROT13 result with the provided target to detect any positional swap. Apply the same two-step rule to the new source.
Step-by-Step Solution:
ROT13 of P S Q R gives C F D E.Target is C F E D, so the last two letters are swapped relative to the pure ROT13 output.Now apply the same rule to J M K L.ROT13 of J M K L → W Z X Y.Swap the last two positions → W Z Y X.Therefore the answer is WZYX.Verification / Alternative check:If we reverse the swap and ROT13 on WZYX, we recover JMKL, confirming symmetry of the transformation.
Why Other Options Are Wrong:
- UVXZ/YVZX/YXZW: These do not match the specific ROT13-then-swap pattern demonstrated by the example.
Common Pitfalls:Stopping after ROT13 without noticing the slight reordering; attempting a uniform Caesar shift instead of the 13-rotation.
Final Answer:WZYX
