Coding-Decoding

Coding-Decoding

Coding and decoding are popular topics in the reasoning ability sections of exams. It involves understanding patterns, rules, or transformations applied to letters, numbers, or symbols and then decoding or encoding a given set of information based on those patterns. Here's an example of a coding-decoding question in reasoning ability:

Example 1: If "PENCIL" is coded as "RGPJQN," how would you code "ERASER"?

Solution: By observing the given coding pattern, each letter in the word is shifted two positions forward in the English alphabet. Applying the same pattern to "ERASER," we get "GTDUHT."

Example 2: If "FLOWER" is coded as "IMRYHU," how would you code "BLOSSOM"?

Solution: In this example, each letter in the word is replaced by the corresponding letter two positions ahead in the English alphabet. Applying the same pattern to "BLOSSOM," we get "DORRUOQ."

Example 3: If "CAT" is coded as "FDT" and "DOG" is coded as "GPH," how would you code "ELEPHANT"?

Solution: In this case, each letter in the word is replaced by the corresponding letter three positions ahead in the English alphabet. Applying the same pattern to "ELEPHANT," we get "HOHPSKDW."

Example 4: If "TRAIN" is coded as "WLVDO," how would you code "BUS"?

Solution: In this example, each letter in the word is replaced by the corresponding letter, counting backward in the English alphabet. Applying the same pattern to "BUS," we get "YXP."

Example 5: If "APPLE" is coded as "MKKPC," how would you code "BANANA"?

Solution: Here, each letter in the word is replaced by the corresponding letter, counting forward and backward alternatively in the English alphabet. Applying the same pattern to "BANANA," we get "ZBMZMZ."

These examples demonstrate different coding and decoding patterns, such as shifting letters forward or backward, replacing letters with corresponding ones, or using alternate patterns. It is important to carefully analyse the given examples, identify the coding pattern or rule, and consistently apply it to decode or encode the given information accurately. Regular practise with coding and decoding problems can enhance your skills in this area.

Coding-Decoding questions can vary in complexity, involving different types of patterns, rules, or transformations. It's important to carefully analyse the given examples, identify the patterns or rules, and apply them consistently to decode or encode the given information accurately. Practise and familiarity with different types of coding and decoding patterns can help improve your skills in this area.
