Coding-decoding IBPS RRB exam is an important subject in the logic section of 2025, often asked in both prelims and main. It tests a candidate’s ability to decod logical thinking, pattern recognition and systematic information. Understanding different types of coding patterns and practicing different types of questions can help improve the speed and accuracy in the exam. In this article, we have provided important coding-decoding questions with a wide solution to help strengthen the subject effectively.
What is coding-decoding
Coding-decoding is an important part of the logic capacity section in IBPS RRB exams. It tests a candidate’s ability to understand 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, the letter is replaced by other letters after a specific pattern.
- Number coding: Numbers change or a combination of letters and numbers is used.
- Symbol coding: Symbols replace letters or numbers.
- Replacement coding: The words are replaced by some codes or symbols.
- Mixed coding/decoding: A combination of above types.
Major strategies to solve coding-decoding questions
- Identify the pattern: See for frequent patterns in the code provided.
- Compare elements: Compare the words coded with their respective basic words to identify the rule.
- Practice regularly: Regular practice helps to recognize the normal coding patterns quickly.
