In a certain code, SHIP is written as HSRK. How is KEY written in that code?

💡 Solution & Explanation

Each letter is replaced by its opposite letter in the alphabet (A ↔ Z, B ↔ Y, C ↔ X, and so on). A letter and its opposite always add up to 27 in position: S (19) → H (8), H (8) → S (19), I (9) → R (18), P (16) → K (11). For KEY: K → P, E → V, Y → B. So the code is PVB.
