Mixed transform – ROT13 with a minor positional swap pattern PSQR : CFED :: JMKL : ?

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:

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
