Alphabet Transformation Logic Puzzle

The question requires transforming letters within given words based on specific alphabetical rules and then counting the resulting words that contain no vowels.

Transformation Rules

  • Vowels (A, E, I, O, U): Replace with the next letter in the alphabet (e.g., A becomes B, U becomes V).
  • Consonants: Replace with the preceding letter in the alphabet (e.g., S becomes R, N becomes M).

Applying Rules to Words

Let's transform each word step-by-step:

  1. SUN
    • S (consonant) is replaced by R (preceding letter).
    • U (vowel) is replaced by V (following letter).
    • N (consonant) is replaced by M (preceding letter).
    • Result: RVM
  2. RAT
    • R (consonant) is replaced by Q (preceding letter).
    • A (vowel) is replaced by B (following letter).
    • T (consonant) is replaced by S (preceding letter).
    • Result: QBS
  3. HIT
    • H (consonant) is replaced by G (preceding letter).
    • I (vowel) is replaced by J (following letter).
    • T (consonant) is replaced by S (preceding letter).
    • Result: GJS
  4. BEGIN
    • B (consonant) is replaced by A (preceding letter).
    • E (vowel) is replaced by F (following letter).
    • G (consonant) is replaced by F (preceding letter).
    • I (vowel) is replaced by J (following letter).
    • N (consonant) is replaced by M (preceding letter).
    • Result: AFFJM

Identifying Words Without Vowels

Now, let's check each transformed word for the presence of vowels (A, E, I, O, U):

  • RVM: Contains no vowels.
  • QBS: Contains no vowels.
  • GJS: Contains no vowels.
  • AFFJM: Contains the vowel 'A'.

Final Count

There are three transformed words (RVM, QBS, GJS) that do not contain any vowels.
