Read the first 7 Coding-Decoding flashcards as text

  1. In a code language, each letter is shifted 3 places forward in the alphabet (Z wraps to C). If 'ACE' is coded as 'DFH', what is the code for 'SKY'?

    Answer: VNB

    S+3=V, K+3=N, Y+3=B (Y is the 25th letter; 25+3=28, wraps to 2nd letter=B), giving VNB.

  2. If 'RAIN' is coded as 'SBJO' (each letter shifted +1), what is the code for 'SNOW'?

    Answer: TOPX

    S+1=T, N+1=O, O+1=P, W+1=X, giving TOPX.

  3. In a code, each letter is replaced by the letter 2 places before it (circular: A-2=Y). If this rule applies, what is the code for 'HEAT'?

    Answer: FCYR

    H-2=F, E-2=C, A-2=Y (circular), T-2=R, giving FCYR.

  4. In a code, each letter is replaced by its mirror opposite in the alphabet (A↔Z, B↔Y, C↔X, etc.). What is the code for 'LOVE'?

    Answer: OLEV

    L(12)→O(15), O(15)→L(12), V(22)→E(5), E(5)→V(22), giving OLEV.

  5. If 'CAT' is coded as 'GEX' using a +4 letter shift, what is the code for 'DOG'?

    Answer: HSK

    D+4=H, O+4=S, G+4=K, giving HSK.

  6. In a certain code, 'PARK' is written as 'QBSL' (each letter +1). What word does 'CBOL' decode to?

    Answer: BANK

    Reversing the +1 shift: C-1=B, B-1=A, O-1=N, L-1=K, giving BANK.

  7. If 'MANGO' is coded as 'NBOHP' (each letter +1), what is the code for 'LEMON'?

    Answer: MFNPO

    L+1=M, E+1=F, M+1=N, O+1=P, N+1=O, giving MFNPO.
