Coding-Decoding Quiz 2

Each letter is shifted by +1. W+1=X, I+1=J, N+1=O, T+1=U, E+1=F, R+1=S. Applying this to SUMMER: S+1=T, U+1=V, M+1=N, M+1=N, E+1=F, R+1=S.

Each letter is shifted by +1. D+1=E, O+1=P, C+1=D, T+1=U, O+1=P, R+1=S. Applying this to NURSE: N+1=O, U+1=V, R+1=S, S+1=T, E+1=F.

Each letter is shifted by +1. P+1=Q, L+1=M, A+1=B, N+1=O, E+1=F, T+1=U. Wait, that gives QMBOFV, but the given code is QMBOFV. Let me check: P+1=Q, L+1=M, A+1=B, N+1=O, E+1=F, T+1=U. This gives QMBOFU, not QMBOFV. Let me recalculate. P->Q (+1), L->M (+1), A->B (+1), N->O (+1), E->F (+1), T->V (+2). The pattern is not consistent. Let me assume it’s +1 for all. Applying this to ROCKET: R+1=S, O+1=P, C+1=D, K+1=L, E+1=F, T+1=U.

Each letter is shifted by -1. M-1=L, O-1=N, B-1=A, I-1=H, L-1=K, E-1=D. Wait, that gives LNAHKD, not LNAJKD. Let me recalculate. M-1=L, O-1=N, B-1=A, I-1=H, L-1=K, E-1=D. This gives LNAHKD. The given code is LNAJKD. Let me check if there’s a different pattern. M->L (-1), O->N (-1), B->A (-1), I->J (+1), L->K (-1), E->D (-1). The pattern is mostly -1 except for I->J which is +1. Let me assume the pattern is -1 for all letters. Applying this to LAPTOP: L-1=K, A-1=Z, P-1=O, T-1=S, O-1=N, P-1=O.

Each letter is shifted by +1. H+1=I, O+1=P, U+1=V, S+1=T, E+1=F. Applying this to GARDEN: G+1=H, A+1=B, R+1=S, D+1=E, E+1=F, N+1=O.

Each letter is shifted by +1. S+1=T, C+1=D, H+1=I, O+1=P, O+1=P, L+1=M. Applying this to COLLEGE: C+1=D, O+1=P, L+1=M, L+1=M, E+1=F, G+1=H, E+1=F.

Each letter is shifted by +1. T+1=U, I+1=J, G+1=H, E+1=F, R+1=S. Applying this to ZEBRA: Z+1=A, E+1=F, B+1=C, R+1=S, A+1=B.

Each letter is shifted by +1. F+1=G, R+1=S, I+1=J, E+1=F, N+1=O, D+1=E. Applying this to ENEMY: E+1=F, N+1=O, E+1=F, M+1=N, Y+1=Z.

Each letter is shifted by +3. M+3=P, A+3=D, N+3=Q, G+3=J, O+3=R. Applying this to APPLE: A+3=D, P+3=S, P+3=S, L+3=O, E+3=H.

The word is written in reverse order. COMPUTER becomes RETUPMOC, then each letter is shifted by +1: R+1=S, E+1=F, T+1=U, U+1=V, P+1=Q, M+1=N, O+1=P, C+1=D. Wait, that gives SFUVQNPD, not RFUVQNPC. Let me recalculate. COMPUTER reversed is RETUPMOC. But the code is RFUVQNPC. Let me check if it’s just reversed: COMPUTER reversed is RETUPMOC. The code RFUVQNPC doesn’t match. Let me try a different approach. If we reverse COMPUTER, we get RETUPMOC. Then apply +1 to each: R+1=S, E+1=F, T+1=U, U+1=V, P+1=Q, M+1=N, O+1=P, C+1=D = SFUVQNPD. This doesn’t match the given code. Let me try another approach. Maybe the pattern is different. Let me check position by position: C->R (+15), O->F (-9), M->U (+8), P->V (+6), U->Q (-4), T->N (-6), E->P (+11), R->C (-15). The pattern is not consistent. Let me assume the word is simply reversed: COMPUTER -> RETUPMOC. But the given code is RFUVQNPC. Let me check if there’s a consistent shift: R->R (0), E->F (+1), T->U (+1), U->V (+1), P->Q (+1), M->N (+1), O->P (+1), C->C (0). This is not consistent either. Let me assume the pattern is to reverse the word and then apply a Caesar cipher with shift +1, but the first and last letters remain unchanged. COMPUTER reversed is RETUPMOC. Apply +1 to middle letters: R, E+1=F, T+1=U, U+1=V, P+1=Q, M+1=N, O+1=P, C. This gives RFUVQNPC, which matches! So for KEYBOARD: Reverse to get DRAOBYEK. Apply +1 to middle letters: D, R+1=S, A+1=B, O+1=P, B+1=C, Y+1=Z, E+1=F, K. This gives DSBPCZFK.

Each letter is shifted by +1. P+1=Q, E+1=F, N+1=O, C+1=D, I+1=J, L+1=M. Applying this to RUBBER: R+1=S, U+1=V, B+1=C, B+1=C, E+1=F, R+1=S.

The code is the sum of position values of letters. BOARD: B(2)+O(15)+A(1)+R(18)+D(4)=40. But given as 36, so subtract 4. MILTON: M(13)+I(9)+L(12)+T(20)+O(15)+N(14)=83. But given as 79, so subtract 4. STABLE: S(19)+T(20)+A(1)+B(2)+L(12)+E(5)=59. Subtract 4 = 55.
