 Coding-Decoding – Verbal Reasoning (Dr. R.S. Aggarwal)

Coding-Decoding is a common topic in verbal reasoning, where a word, number, or sentence is transformed into a particular pattern. Your task is to find the logic behind the transformation and decode it.

 Types of Coding-Decoding Questions

 Alphabet Coding

In this type, each letter in a word is replaced by another letter based on a pattern.

Example 1:
 If CAT is coded as DBU, how is DOG coded?

Solution:

• C → D (+1), A → B (+1), T → U (+1)
• Following the same rule, DOG → EPH
  Answer: EPH

 Numerical Coding

Numbers are assigned to letters or words based on a pattern.

Example 2:
 If A = 1, B = 2, C = 3 and so on, what is the code for WORD?

Solution:

• W = 23, O = 15, R = 18, D = 4
  Answer: 23-15-18-4

 Letter to Number Coding

Each letter is replaced with a number based on its position in the alphabet.

Example 3:
 If SUN = 19 21 14, what is RAIN?

Solution:

• R = 18, A = 1, I = 9, N = 14
  Answer: 18 1 9 14

 Mixed Coding

Multiple words are coded together, and the pattern must be identified.

Example 4:
 If “Sky is blue” is coded as “1 2 3”, and “Blue is beautiful” is coded as “3 2 4”, what is the code for “Beautiful”?

Solution:

• “Blue” = 3, “is” = 2
• “Beautiful” = 4
  Answer: 4

 Important Tricks to Solve Coding-Decoding

Observe letter shifts (+1, -1, reverse order).
Convert letters to numbers (A=1, B=2, … Z=26).
Look for common patterns in multiple codes.
Practice frequently to recognize patterns quickly.
