Question 1
If each letter is shifted +4, code the word SUN.
Show solution
S+4=W, U+4=Y, N+4=R → WYR
Question 2
If each letter is shifted −3, code the word PLANT.
Show solution
P−3=M, L−3=I, A−3=X (1−3=−2→24=X), N−3=K, T−3=Q → MIXKQ
Question 3
If the alphabet is reversed (A↔Z), code the word MOON.
Show solution
M(13)→N(14), O(15)→L(12), O→L, N(14)→M(13) → NLLM (Each pair sums to 27 ✔)
