<thinking>Let's approach this step-by-step:
We'll work through this logically (CoT):

Step 1: What does the inquiry asking me to do?
Determine the quantity of letter "a" in the word "Xerxes"

Step 2: Deconstruct the word.

The correct word is "Xerxes", not "xmrxes". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. X
2. E
3. R
4. X
5. E
6. S

Step 5: Pinpoint the positions of the letter "a".
The letter "a" does not appear in the word.

Step 6: Sum up the letters.
R: 1, S: 1, E: 2, X: 2

Step 7: Inspect the letters we quantified.
