Coding & Decoding : Questions and tips

This topic is part of the reasoning ability curriculum, and applicants must decode a code given in the question and respond accordingly, as the name implies. It is one of the most prevalent themes on which competitive tests, particularly bank exams, pose questions.

Types of questions:

Questions on coding and decoding come in a variety of forms.

These are some of them:

• Coding in Alphabetical Order
• Coding in Numbers
• Coding Based on Symbols
• Values of Alphabet-Symbol-Numerical Coding Substitution Coding
• Unravel Coding

Tips for Coding & Decoding Section Order to prepare :

To aid applicants in their preparation for forthcoming bank and SSC examinations, we've compiled a list of helpful hints for approaching the Coding-Decoding test questions using the new pattern in a more efficient and effective manner. Candidates who understand these pointers will be able to answer coding and decoding problems with ease in forthcoming bank and SSC examinations. A few pointers to help candidates tackle coding decoding questions in forthcoming competitive examinations are listed below: Read the question attentively and jot down any crucial codes that come up. Attempt to decipher the question's coding. Candidates should be aware that the same style of decoding might be used for a variety of questions. Eliminate the unneeded values and try to simplify the code using the elimination procedure. Solve more and more practice problems to have a better understanding of the idea and to easily score higher on questions based on this topic.

‘HEDONISM’ is written as ‘QFGJOUKP’.

Check the pattern here:

H + 2 = J ,O +2 =Q (Positions interchanged)

E + 2 = G, D + 2 = F (Positions interchanged)

N +2 = P, M+ 2 = O (Positions interchanged)

I + 2 = K, S + 2 = U (Positions interchanged) Follow the simple pattern and get the answer.
