Difficulty: MediumCoding and Decoding

In a corporate access control mechanism, security codes are generated by applying a specific transformation logic to employee department names. In this system, the word PLANT is coded as SOZQW, and the word TRAIN is coded as WUZRQ. Based on the same logic, how will the word GLOBE be coded in this system?

Answer

The correct answer is JOLEV.
The coding logic treats consonants and vowels differently. Consonants are shifted forward by 3 alphabetical positions (e.g., P becomes S, G becomes J, L becomes O). Vowels are replaced by their reverse alphabetical counterpart, which represents their position from the end of the alphabet (e.g., A becomes Z, O becomes L, E becomes V). Applying this to GLOBE: G (+3) is J, L (+3) is O, O (reverse) is L, B (+3) is E, and E (reverse) is V. This yields JOLEV.

Step-by-Step Solution

1
Analyze the first example (PLANT -> SOZQW) to identify the transformation rule.
The consonants P, L, N, T shift forward by 3 alphabetical positions to become S, O, Q, W. The vowel A is replaced by its reverse alphabetical counterpart Z (27 - 1 = 26).
To determine how consonants and vowels are uniquely handled within the coding structure.
2
Verify the established logic using the second example (TRAIN -> WUZRQ).
The consonants T, R, N shift forward by 3 to W, U, Q. The vowels A and I are replaced by their reverse positions Z and R (27 - 9 = 18).
To confirm the dual-rule pattern applies consistently across all provided examples.
3
Apply the confirmed dual-rule logic to the target word GLOBE.
G (+3) becomes J; L (+3) becomes O; O (reverse, 27 - 15) becomes L; B (+3) becomes E; E (reverse, 27 - 5) becomes V.
To generate the final encoded sequence according to the established transformation parameters.

Key Concept

Identifying complex dual-rule alphabetic patterns distinguishing between consonants and vowels.
