In the word **MARATHON**, if all the vowels are replaced by their opposite letters in the English alphabet (i.e., A ↔ Z, E ↔ V, I ↔ R, O ↔ L, U ↔ F) and all the consonants are replaced by the letter that comes **two places before** them in the English alphabet, how many letters are repeated in the newly formed word?

Question

Accepted Answer

**Solution:**

1. Identify vowels and consonants in the word **MARATHON**:
   - Vowels: A, A, O
   - Consonants: M, R, T, H, N

2. Replace vowels with their opposite letters in the English alphabet:
   - A → Z (since A is the 1st letter, opposite is 26th letter Z)
   - O → L (O is 15th letter, opposite is 12th letter L)

So vowels A, A, O become Z, Z, L respectively.

3. Replace consonants with the letter two places before them:
   - M (13th letter) → K (11th letter)
   - R (18th letter) → P (16th letter)
   - T (20th letter) → R (18th letter)
   - H (8th letter) → F (6th letter)
   - N (14th letter) → L (12th letter)

4. Now, the transformed word is:
   - M → K
   - A → Z
   - R → P
   - A → Z
   - T → R
   - H → F
   - O → L
   - N → L

So the new word is: **K Z P Z R F L L**

5. Count the repeated letters:
   - Z appears twice
   - L appears twice

Total repeated letters = 2
