- UZDQ
Show the answer and the worked solution
Correct answer: A. VZDQ
Worked solution
- The shift is +3.
- S→V, W→Z, A→D, N→Q.
- The code is VZDQ.
Answer: VZDQ.
The idea
W + 3 wraps to Z without going past it. Only letters beyond W would wrap round to the start of the alphabet.
Shortcut. The options differ at the first, second and last letters: S+3 = V, W+3 = Z and N+3 = Q. Only VZDQ has all three.
Common trap. "VYDQ" — counting W itself as the first of the three steps (W, X, Y); counting starts at the next letter, X, Y, Z, so W becomes Z.
