Coding-decoding is an important part of the logic capacity section in IBPS RRB PO and Clerk 2025 exam. The subject assesses the logical thinking and analytical skills of the candidate by presenting specific patterns or rules that follow the coded messages. This includes various types of questions where words, letters or numbers are encrypted into a particular format and the candidate must decode the argument to reach the correct answer.
Coding-decoding for IBPS RRB PO and Clerk 2025
With the emerging trend of banking examinations, coding-decoding questions have become more diverse and challenging. Techniques such as alphabet shifting, reverse order coding, alphanumeric-identical coding and matrix-based decoding are often used. Mastery in these techniques not only helps in rapid resolving such questions, but also improves overall accuracy and promotes performance in a competitive examination environment.
Types and techniques of coding-decoding for IBPS RRB PO/Clerk
Coding-decoding is an important subject in IBPS RRB PO and Clerk Examination Capacity Section. It assesses the ability of the candidate to identify patterns, implement logical rules and decode a given code efficiently. Questions in this section may be based on various techniques and types of coding. Below are the major types and techniques of coding-decoding that candidates should master for IBPS RRB PO and Clerk Examination.
1. Binary coding-decoding
In binary coding-decoding, the decimal number is represented in binary form, which uses only 0s and 1s. Candidates need to convert a decimal number into binary and vice versa. This type of question tests a candidate’s proficiency in number systems.
Technology:
Example:
-
Decide 12 = binary 1100
-
Binary 1010 = decimal 10
2. Letter-to-letter coding-decoding
In this type of coding, a particular pattern or rule is applied to letters in code or decod words. Operations are usually used to move letters, add values ​​or reduce values ​​or swapping positions.
Technology:
-
Alphabet Shifting: The letters are transferred to the alphabet by a certain number. For example, transfer each letter from 3 posts.
-
Reverse alphabet coding: Each letter is replaced by contrast in the alphabet (a = z, b = y, etc.).
Example:
3. Chinese coding-decoding
In Chinese coding-decoding, words or phrases are rearranged in a specific order. All words can have the same meaning but appear in different scenes. The candidate needs to identify the correct pattern or code based on the sequence of words.
Technology:
Example:
-
Given “mango = 1, apple = 2, banana = 3”, determine the correct order of words based on their code.
4. Conditional coding-conducting
Conditional coding-decoding questions include implementing certain conditions or operations to decod the message given. Conditions may include arithmetic operations, changes, or patterns that need to be recognized and implemented.
Technology:
-
Implementing conditions: Conditions such as transferring letters, converting numbers or conducting arithmetic should be applied to decodes the message.
-
Operations on letters or numbers: Addition, subtraction or division can be used to decod the message.
Example:
5. Number-to-Number Coding-Dokoding
This type of coding includes the number being used in various forms, where each number can represent another number based on a particular rule. This may include simple arithmetic operations, sequences, or status codes.
Technology:
-
Arithmetic Operations: Numbers can be added, reduced or multiposed to create a code.
-
Number sequence: The numbers are part of a sequence, and the candidate needs to identify the next or missing number in the pattern.
Example:
6. Letter-to-numbers coding-decoding
In letter-to-numbers coding-decoding, each letter of the alphabet is assigned a related number based on its position (A = 1, B = 2, C = 3, etc.). This method can be used alone or in combination with other functions such as joint or transfer.
Technology:
-
Letter for status conversion: Convert letters into numbers (A = 1, B = 2, etc.) and apply the given pattern or rule.
-
Mixing letters and numbers: Letters and numbers are used in combination, candidates need to decode both elements.
Example:
-
“Cat12” can be decoded as C = 3, A = 1, T = 20, and 12 can represent an additional position or shift.
7. Symbolic coding
In symbolic coding-decoding, symbols or characters are used in place of letters or numbers. These symbols can represent specific letters or numbers, and the candidate needs to decode them based on a key or pattern.
Technology:
-
Symbol-to-symbol or symbol-numbers conversion: Each symbol matches a specific letter or number.
-
Identifying the symbol pattern: Recognizing and implementing rules for decoding symbols.
Example:
8. Word-based coding-decoding
In Word-based coding-decoding, the whole words are coded in other words based on patterns, rules or operations. This may include re -organizing letters, changing the situation, or applying the shift.
Technology:
-
Refilling letters or words: The letters of a word are rearranged to create a new word.
-
Implementing Shift or Operation: Focus on letter-to-level coding but on word-level decoding.
Example:
