In a certain code, RAIN is written as IZRM. How is TREE 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: R (18) → I (9), A (1) → Z (26), I (9) → R (18), N (14) → M (13). For TREE: T → G, R → I, E → V, E → V. So the code is GIVV.
