In a code, each letter is replaced by the letter in the same position counting from the other end of the alphabet (so A becomes Z and B becomes Y). DOG is written as WLT. How is TRAIN written?

Answer and explanation

Correct answer: D. GIZRM

  1. Step 1: A pairs with Z, B with Y, C with X, and so on, so the two letters in each pair add up to 27 in position. Step 2. Apply this to each letter of TRAIN: T to G, R to I, A to Z, I to R, N to M. Step 3. The code is GIZRM. Answer: GIZRM. Why not the others: USBJO: This moves each letter one place forward instead of reversing the alphabet. NIART: This reverses the order of the letters instead of the alphabet. GIZRN: This codes all letters but the last one.
