Wondering how to answer the Coding and Decoding questions? This post shall provide the most important coding and decoding questions for DU JAT and other entrance exams.

You can also know the steps to answer these questions easily. So, what are you waiting for? Read the complete post to know more about coding and decoding.

What is Coding and Decoding?

Coding is a process of encrypting a word or a number in a particular pattern considering a set of rules. Decoding is the process of decrypting the pattern into the original form from the given code.

Examples of Coding and Decoding

Various types of questions can be asked from coding and decoding, however here are three types explained in detail with an example.

Letter Coding

• TGMJCR
• SGMJCQ
• TGMJCQ
• TGWCQ

Number/Symbol Coding

If CHAIR is written as ‘12345’, RENT is written as ‘5678’, and then REAR is written as.

• 5635
• 5356
• 5365
• 5653
