Difficulty: Medium
Correct Answer: RAX : OXU
Explanation:
Introduction / Context:
This question asks you to find another pair of letter groups that follows the same coding rule as the given pair FOM : CLJ. Instead of decoding and re coding a new word, you need to compare whole pairs and see which option uses the same position shift between its first and second elements.
Given Data / Assumptions:
Concept / Approach:
We must first determine how each letter of FOM converts to CLJ. If that transformation is a constant shift by the same number of positions for all three letters, we then look for a candidate pair where the same constant shift is applied from its first group to its second group.
Step-by-Step Solution:
Verification / Alternative check:
Check other pairs briefly. For RQS : POQ the shifts are not consistently minus three for all letters. JKN : MNQ moves forward, not backward. ACD : CEF moves forward by varying amounts. QRS : TUV shows a forward shift of plus two or plus three. Only RAX : OXU shows a uniform shift of minus three for every position, matching FOM : CLJ.
Why Other Options Are Wrong:
Common Pitfalls:
Some candidates may only check the first letter or become distracted by visual similarity between letter groups. It is important to compute numeric positions for every letter in at least the strongest candidate pair and confirm that the same constant shift works across all letters before deciding.
Final Answer:
The pair RAX : OXU follows the same minus three pattern as FOM : CLJ.
