Coding-Decoding Reasoning Questions, Tricks, Examples with Solution in Hindi

Types Of Coding-Decoding Reasoning

Questions appeared in the banking exams from coding-decoding are of various types. Candidates can check all the types of coding-decoding reasoning here.

Binary Coding-Decoding

The binary number is made by 0’s and 1’s complements. So, a coded binary number consists of two processes. One is conversion of binary to decimal and another is decimal to binary.

Letters to Letters Coding-Decoding

In letter-letter coding, the candidate will need to get phrases from letters. Getting phrases from letters that we set up according to a certain sample or code is the subject of this segment on Letter-letter coding. In general, we are saying that Getting phrases from letters is an installation to choose the candidate’s capacity to decipher the guideline of thumb that codes a specific word/message and break the code. In this type of coding-decoding, the alphabet of words is added with various operations like addition, subtraction, etc.

Chinese Coding-Decoding

In these questions, all words have the same meaning but in different orders, candidates have to find out the code of every word.

Conditional Coding-Decoding

In this type of coding-decoding question, a few conditions and operations need to apply, candidates have to understand these conditions and then answer the questions.

Numbers to Numbers Coding-Decoding

In this type of coding-decoding question in the reasoning ability section, only numbers are used in various forms.

Letters to Numbers Coding-Decoding

In these types of questions, letters and numbers are used like CAT12, ABE45, etc.

Coding Decoding Reasoning Tricks

Coding Decoding Reasoning Tricks: The weightage of the questions asked from the coding-decoding reasoning topic is mostly 4-6 marks and though may seem time-consuming, they are easy to solve and this is a scoring topic of the reasoning section. Here we have provided some tips tricks & concepts to solve coding-decoding reasoning questions.

Coding Decoding Tips & Tricks

  • Try to understand the pattern of codes that are given to you in question. You can use the hit-and-trial method and check for various rules.
  • While solving the coding-decoding questions try to find out the relation between the two terms, the given word and its codes should be done first.
  • The first thing while attempting coding-decoding questions is to approach them step by step. Check the code and deduce the pattern. The pattern must be visible as soon as you see the code. Try and match the pattern/ logic by arranging and rearranging the letters of the codes.
  • You can use the elimination method to simplify the quote and remove the unnecessary values.
  • Solving a bunch of questions on daily quizzes will be helpful for you in your preparation.

Mistakes to Avoid in Coding-Decoding Reasoning

Coding-Decoding can be sometimes challenging, often prone to certain blunders that can affect the overall marks. To maximize performance in this topic, here are some common mistakes that can be avoided in Coding-Decoding

  • Neglecting the Coding Pattern: One of the most frequent mistakes is diving straight into decoding without thoroughly analyzing the coding pattern. Rushing through the question without understanding the logic behind the coding can lead to incorrect answers.
  • Misinterpreting Symbols or Characters: Symbols or characters may be used to represent letters, numbers, or words. Misinterpreting these symbols or applying incorrect substitutions can result in erroneous decoding.
  • Ignoring Reverse Coding: Reverse coding, or decoding the given code to identify the original word or phrase, is an essential aspect of Coding-Decoding reasoning. Failing to consider reverse coding can limit your ability to accurately decode messages. Always explore both forward and reverse coding possibilities to ensure a comprehensive understanding of the coding scheme.
  • Not Checking for Consistency: Neglecting to check for consistency across all conditions can result in incorrect decoding. Verify that the decoded message aligns with all the given rules or conditions to ensure accuracy.
  • Lack of Practice: Practice is key to mastering Coding-Decoding reasoning. Failing to devote sufficient time to practice and familiarize yourself with different coding patterns and techniques can hinder your performance.
