Coding-Decoding is a crucial topic in the Reasoning section of the IBPS RRB Exam 2025, frequently asked in both Prelims and Mains. It tests a candidate’s logical thinking, pattern recognition, and ability to decode information systematically. Understanding different types of coding patterns and practicing a variety of questions can help improve speed and accuracy in the exam. In this article, we have provided important Coding-Decoding questions with detailed solutions to help you strengthen this topic effectively.
What is Coding-Decoding
Coding-Decoding is a crucial part of the Reasoning Ability section in the IBPS RRB exams. It tests a candidate’s ability to decipher a given code language. In these questions, information is given in a coded form, and candidates need to decode it using a specific pattern or rule.
Types of Coding-Decoding Questions
- Letter Coding: Here, alphabets are replaced by other alphabets following a specific pattern.
- Number Coding: Numbers replace letters or a combination of letters and numbers is used.
- Symbol Coding: Symbols replace letters or numbers.
- Substitution Coding: Words are replaced by certain codes or symbols.
- Mixed Coding/Decoding: A combination of the above types.
Key Strategies for Solving Coding-Decoding Questions
- Identify Patterns: Look for consistent patterns in the codes provided.
- Compare Elements: Compare coded words with their corresponding original words to identify the rule.
- Practice Regularly: Regular practice helps in quickly recognizing common coding patterns.
