Reason Coding Decoding in Reasoning
Coding-decoding questions involve substituting letters, numbers, or symbols according to a specific rule or cipher. The key is to identify the encoding rule by analyzing the given examples, then apply it consistently to decode or encode new information. Rules may involve position shifts (Caesar cipher), reversal, substitution tables, or mathematical operations.
Common coding methods include: (1) Alphabet shift—each letter moves a fixed number of positions (A→D means shift by 3), (2) Reverse alphabet—A↔Z, B↔Y, etc., (3) Position-based coding—using a keyword or sequence, (4) Substitution cipher—each letter has a unique replacement, (5) Number-letter conversion—using numeric values.
To decode: Analyze 2-3 examples to identify the rule, verify the rule works for all examples, apply it to the question. Always work systematically and double-check by encoding/decoding the original example to confirm your rule is correct.
