Identify Vowels and Consonants in PASTRY
In the word P A S T R Y, the letters are P (Consonant), A (Vowel), S (Consonant), T (Consonant), R (Consonant), Y (Consonant).
Apply Transformation Rules
Consonants move to the immediately preceding letter (-1): P тЖТ O, S тЖТ R, T тЖТ S, R тЖТ Q, Y тЖТ X. Vowels move to the immediately succeeding letter (+1): A тЖТ B.
Form the New Letter Group and Count Vowels
The newly formed group of letters is O, B, R, S, Q, X. Checking each letter for vowels (A, E, I, O, U): None of these letters are vowels. Therefore, the number of vowels present is None (0).
A: Two is incorrect because there are no two vowels in the new string. C: Three is incorrect as no three vowels are formed. D: One is incorrect since letter B is a consonant, leaving zero vowels.
D is correct because applying the given rules to PASTRY yields OBRSQX, which contains zero vowels (None).
Always verify whether the transformed letter itself becomes a vowel or consonant, as letters like A changing to B change from vowel to consonant!
