What Are Coding Decoding Questions?
In Coding Decoding questions, a word, number, or sentence is written in a coded form based on a specific logic or pattern. Candidates are required to
- Decode the given code
- Identify the pattern used
- Find the correct coded or decoded answer
These questions mainly focus on logic rather than speed, making accuracy very important.
Types of Coding Decoding Questions Asked in SBI CBO
Letter Coding
Each letter of a word is replaced by another letter based on
- Alphabetical position
- Forward or backward shifting
- Reverse order
Example patterns include +1, -2, opposite letters, or alphabetical series.
Number Coding
Letters are assigned numerical values, often based on
- Alphabet position A = 1, B = 2
- Reverse order Z = 1, Y = 2
Questions may involve sum, difference, or rearrangement of numbers.
Word Coding
One word is replaced by another word based on a hidden logic.
These questions require identifying the relationship between given pairs.
Substitution Coding
Specific words are replaced with symbols, letters, or other words.
Candidates must decode the correct meaning based on given conditions.
Sentence Coding
An entire sentence is coded word by word.
Questions may ask for the code of a particular word or the meaning of a code.
Step-by-Step Approach to Solve Coding Decoding Questions
Step 1 Understand the Pattern
Carefully observe the given example.
Check whether the coding is based on
- Letters
- Numbers
- Symbols
- Position or sequence
Never assume the pattern before complete analysis.
Step 2 Check Alphabetical Positions
In letter-based questions, write down the alphabet positions.
This helps identify
- Forward or backward movement
- Skipping pattern
- Reverse order logic
Step 3 Look for Consistency
The same logic must apply to all parts of the question.
If a rule fails at any point, discard it and recheck.
Step 4 Eliminate Wrong Options
Use the elimination method.
Remove options that do not follow the identified pattern.
This saves time and improves accuracy.
Example Explanation
If
BANK is coded as DCQP
Logic
B → D (+2)
A → C (+2)
N → Q (+3)
K → P (+5)
Such questions require checking whether the same logic fits all letters. Once the pattern is clear, solving becomes easy.
Common Mistakes to Avoid
- Rushing without understanding the pattern
- Ignoring alphabet positions
- Applying different logic to different parts
- Guessing without elimination
- Spending too much time on one question
Avoiding these mistakes can significantly improve performance.
