Each vowel in the word FANTAIL is changed to the letter immediately following it in the English alphabetical order and each consonant is changed to the letter immediately preceding it in the English alphabetical order. How many letters will appear exactly twice in the group of letters thus formed?
One
Apply the rule to each letter of FANTAIL: vowels (A, I) shift to the next alphabet; consonants (F, N, T, L) shift to the previous alphabet.
F (consonant) → E; A (vowel) → B; N (consonant) → M; T (consonant) → S; A (vowel) → B; I (vowel) → J; L (consonant) → K.
The new group of letters is E, B, M, S, B, J, K.
Frequency count: E → 1, B → 2, M → 1, S → 1, J → 1, K → 1.
Only the letter B appears exactly twice; every other letter appears just once.
Hence, the required answer is One.
