In the given word “PERFECTION”, if all the vowels are changed to their second succeeding letter and all the consonants are changed to their just preceding letter as per alphabetical series, then find which among the following letters are repeated?

The correct option is Only G and Q.

Step-by-step Explanation:

Let's process the given word PERFECTION according to the specified rules:

1. Identify the Vowels and Consonants in the word PERFECTION:

• Consonants: P, R, F, C, T, N

• Vowels: E, I, O

2. Apply the given transformations:

• Vowels: Change to their second succeeding letter (+2 in alphabetical series).

• Consonants: Change to their just preceding letter (-1 in alphabetical series).

3. Transforming each letter one by one:

• P (Consonant) → P - 1 = O

• E (Vowel) → E + 2 = G

• R (Consonant) → R - 1 = Q

• F (Consonant) → F - 1 = E

• E (Vowel) → E + 2 = G

• C (Consonant) → C - 1 = B

• T (Consonant) → T - 1 = S

• I (Vowel) → I + 2 = K

• O (Vowel) → O + 2 = Q

• N (Consonant) → N - 1 = M

4. Form the new set of letters:

The transformed word becomes: O G Q E G B S K Q M

5. Check for repeated letters in the new sequence:

• Letter G appears 2 times.

• Letter Q appears 2 times.

• All other letters (O, E, B, S, K, M) appear only once.

Therefore, the letters that are repeated are Only G and Q.
