Coding-Decoding Questions with Solutions
Coding-decoding questions give a word, number or sentence written in a secret code and ask you to work out the rule, then apply it to a new word. This topic covers letter coding (shifting letters forward or backward), number coding, substitution coding, mixed letter-number-symbol coding, and sentence or word-group coding. The key skill is spotting the pattern quickly. Memorising the position of each letter in the alphabet (A = 1 to Z = 26) and its reverse position (A = 26 to Z = 1) speeds up most letter-shift questions. For sentence coding, compare two sentences that share a word to find which code belongs to it. Check your rule against every letter before using it, since many questions use different shifts for alternate letters. Practise the coding-decoding questions below, each with a step-by-step solution showing how the pattern is found.
