Each letter is shifted by +1. B+1=C, I+1=J, R+1=S, D+1=F. So, BIRD is CJSF.

Each letter in 'FISH' is shifted by +1 to get 'GJTI'. Similarly, 'BIRD' becomes 'CJSF'.

The code reverses the order of the digits, so '456' becomes '654'.

The code reverses the digits, so '456' becomes '654'.

The code reverses the order of the numbers: 1->A, 2->B, 3->C. Thus, 4->D, 5->E, 6->F, so 456 is FED.

'123456' combines both codes; thus it means CATDOG.

'C' is the 3rd letter, 'A' is the 1st, 'T' is the 20th, so 'D' is 4, 'O' is 15, 'G' is 7, thus 'DOG' is '4157'.

Each letter is shifted by +1: C->D, I->J, R->S, C->D, L->M, E->F. Therefore, S->T, Q->R, U->V, A->B, R->S, E->F, so SQUARE is TROFBS.

Each letter corresponds to its position in the alphabet: D=4, O=15, G=7. Thus, C=3, A=1, T=20, so CAT is 3-1-20.

Each letter is shifted by +1. B+1=C, I+1=J, R+1=S, D+1=F.

Each letter is shifted by +1; thus DOOR becomes EPPQ.

Each letter is shifted by +1. W -> X, O -> P, R -> S, L -> M, D -> E.

Each letter is shifted by +1: M->N, A->B, N->O, G->H, O->P. Thus, APPLE becomes BQQMF.

Each letter is shifted by +1. A->B, P->Q, L->M, E->F. So, APPLE is BQQMF.

Each letter is shifted by +1: P->Q, E->F, N->O. Therefore, PAPER becomes QBOFS.

Each letter is shifted forward by 1. 'C' becomes 'D', 'O' becomes 'P', 'L' becomes 'M', 'L' becomes 'M', 'E' becomes 'F'.

Each letter is shifted forward by 1. 'F' to 'G', 'I' to 'J', 'R' to 'S', 'E' to 'F' gives 'GJTF'.

C=3, A=1, T=20. D=4, O=15, G=7. So, DOG = 4 + 15 + 7 = 26, coded as 4157.

The code assigns numbers based on the position of letters in the alphabet: C=3, A=1, T=20; D=4, O=15, G=7 gives 4157.

Each letter is shifted by +1: F->G, I->J, S->T, H->I. Therefore, B->C, I->J, R->S, D->E, so BIRD is coded as CJSF.

Each letter is shifted forward by 1. 'B' to 'C', 'I' to 'J', 'R' to 'S', 'D' to 'E' gives 'CJSF'.

Each letter is shifted forward by one in the alphabet: B->C, I->J, R->S, D->E.

O is sitting opposite P since N is facing O.

Since P is opposite N and N is next to O, neither N nor O can sit next to P.

In a circular arrangement, if R is to the left of S, then T, being to the right of R, is opposite S.

F is the son of D, who is the brother of C, making F the grandson of A.

E is the daughter of A, as E is the sister of B.

C is the mother of B, and since F is the grandfather, C must have a mother who is the grandmother.

D is the son of A and C, making him the grandson of F.

The combinations that sum to 7 are (1,6), (2,5), (3,4), but (4,5) sums to 9.
