In a certain code, FROG is written as GTRK. How is HAND written in that code?

💡 Solution & Explanation

Compare FROG with GTRK: F → G, R → T, O → R, G → K. The letters move +1, +2, +3, +4 places, one more for each position. Applying the same steps to HAND: H → I, A → C, N → Q, D → H. So the code is ICQH.
