If 'PEN' is '7-22-13', how is 'INK' coded? MCQ with Answer and Explanation

Explanation:
Each letter in the word is shifted +1 step forward in the alphabetical order. P(+1)=Q, E(+1)=F, N(+1)=O. Thus, PEN becomes QFO.

Explanation:
Each letter is shifted +2 steps forward. B(+2)=D, R(+2)=T, U(+2)=W, S(+2)=U, H(+2)=J. BRUSH becomes DTWUJ.

Explanation:
The word is split into pairs and each pair is reversed. FL->LF (Wait, FLIGHT -> ILFGTH means FLI -> ILF, GHT -> THG? No, FLIGHT -> ILFGTH. F, L, I -> I, L, F. G, H, T -> T, H, G? No, it's ILF GTH. Reverse first 3, reverse last 3. FLI->ILF, GHT->THG. TICKET -> TIC->CIT, KET->TEK. CITTEK. If option A is ITKCTE, it implies pairs swapped: TI->IT, CK->KC, ET->TE. ITKCTE.)
