This is a letter-analogy (coding-decoding) problem based on the mirror/reverse-alphabet substitution rule: each letter at position p (counting A = 1) is replaced by the letter at the mirror position (27 − p) — that is, A pairs with Z, B pairs with Y, C pairs with X, and so on — the two positions of any paired letters always add up to 27.

Applying this rule, first to the given pair to confirm it, then to the unknown pair:

1. Verify with XYZ : CBA — X is the 24th letter and C is the 3rd letter, 24 + 3 = 27; Y is the 25th letter and B is the 2nd letter, 25 + 2 = 27; Z is the 26th letter and A is the 1st letter, 26 + 1 = 27. The mirror rule holds for all three letters.

2. Q is the 17th letter, so its mirror position is 27 − 17 = 10, which is J.

3. R is the 18th letter, so its mirror position is 27 − 18 = 9, which is I.

4. S is the 19th letter, so its mirror position is 27 − 19 = 8, which is H.

5. Concatenating the mirrored letters in order gives J, I, H → JIH.

Independent cross-check: counting from the END of the alphabet, Q is the 10th letter from Z, and the 10th letter from A is J — the two counts agree; the same holds for R (9th from the end = I) and S (8th from the end = H), confirming JIH without recomputing.
