In the term “RESPIRATION”, every vowel is replaced with the letter two positions after it in the English alphabet, while every consonant is replaced with the letter immediately before it. Which of the following letters appear more than once in the newly formed letter group?

The correct answer is Only Q and K.

Step-by-step explanation:

Given word: RESPIRATION

We are given the following replacement rules:
1. Every vowel (A, E, I, O, U) is replaced by the letter two positions after it in the English alphabet (+2).
2. Every consonant is replaced by the letter immediately before it in the English alphabet (-1).

Let us apply these rules to each letter of the word RESPIRATION:
• R (Consonant) → Q
• E (Vowel) → E + 2 = G
• S (Consonant) → R
• P (Consonant) → O
• I (Vowel) → I + 2 = K
• R (Consonant) → Q
• A (Vowel) → A + 2 = C
• T (Consonant) → S
• I (Vowel) → I + 2 = K
• O (Vowel) → O + 2 = Q
• N (Consonant) → M

The newly formed letter group is: Q G R O K Q C S K Q M

Now, let us count the frequency of each letter in the new group:
• Q appears 3 times
• K appears 2 times
• G, R, O, C, S, M each appear 1 time

Hence, the letters that appear more than once in the newly formed letter group are Q and K (Option: Only Q and K).
