If the letter-group SOUL transforms into the code VLFO according to a specific alphanumeric rule, which of the following letter-groups represents the word DIRT under the identical rule?

  1. GRUWAnswer
  2. B
    GLUW
  3. C
    WRIG
  4. D
    WLIG

Answer

GRUW
The underlying logical rule distinguishes between consonants and vowels. Consonants are shifted forward by 3 positions in the English alphabet (e.g., S becomes V, L becomes O). Vowels are replaced by their opposite/mirror letter from the reverse alphabetical order (e.g., O becomes L, U becomes F). Applying this rule to DIRT: The consonants D, R, and T shift forward by 3 to become G, U, and W. The vowel I is replaced by its reverse alphabetical counterpart, R. Therefore, the resulting letter-group is GRUW.

Step-by-Step Solution

1
Analyze the transformation from the reference word SOUL to its corresponding code VLFO to deduce the underlying rule.
By examining the alphabetical positions, consonants (S, L) shift forward by 3 positions to become (V, O). Vowels (O, U) are replaced by their opposite/mirror letters from the reverse alphabet (L, F).
Establishing the precise logical coding pattern is necessary to solve the analogy.
2
Categorize the letters in the target word DIRT into consonants and vowels.
Consonants: D, R, T. Vowel: I.
The established rule relies on treating consonants and vowels differently.
3
Apply the respective rules to the categorized letters of DIRT.
D (+3) yields G. I (reverse mirror) yields R. R (+3) yields U. T (+3) yields W. Combining these results in the string GRUW.
Applying the exact established rule provides the final encoded letter-cluster.
