Tricks to Solve Coding Decoding Questions

A bank entrance exam, as we all know, measures your aptitude. The primary areas assessed in a bank admission exam include quantitative aptitude, reasoning ability, English language, and general awareness. Reasoning Ability includes the section ‘Coding-Decoding.' You can either do well or waste a lot of time with little to show for it. It’s directly like the better prepared you are, the higher your score will be on the same.

This article will walk you through the fundamentals of ‘Coding-Decoding' and how to use them to solve challenges. Let's start with a definition of coding and decoding. What kinds of inquiries are posed about this subject?

What Are Coding And Decoding?

• Coding is a method of sending data between a sender and a recipient in an encrypted format, which means no one else can see it.

• The data is encoded before transmission, and when it is received, it is decoded to recover the original data.

• This keeps the information from becoming corrupted and leaked.

After knowing what coding and decoding are, let us further read about what type of questions are asked in bank & SSC exams.

Relevance Of ‘coding-Decoding’ In Reasoning Section

• Coding and decoding questions are asked in a variety of banking and SSC tests, and they are also asked in a variety of other employment exams. The premise and approach are the same; the difficulty level differs.

• The level of difficulty in SSC exams is low to moderate, whereas the level of difficulty in bank exams is high.

• There are 5-7 questions based on ‘Coding and Decoding’ in bank/SSC exams.

• Classification of ‘Coding and Decoding’ questions is as follows:

1. Letter Coding

2. Substitution

3. Mixed Letter Coding

• Mixed Number Coding

Furthermore, Let’s Go On A Fruitful Journey To Know Smart Ways To Solve ‘coding-Decoding’ Questions.

Ever wondered about code language in reasoning and how to solve coding-decoding in logical reasoning? 

Smart Approach On How To Solve Code Language Reasoning Questions 

• Pay attention to the alphabets or digits in the question.

• Look for a pattern or a sequence that it follows. They could be organised in ascending or descending order, in a different order, or in any other method.

• Determine the rule that the alphabets/numbers/words are arranged according to.

Basic Points You Need To Remember Before Solving Any Question Of This Topic.

• Alphabets’ positions (A=1, B=2,……,Y=25, Z=26)

• Opposite position of the alphabet (A=26, B=25,……, Z=1)

• Opposite of each alphabet (A is opposite to Z, B is opposite to Y and so on)

Letter Coding

The alphabets in a word are replaced by other alphabets according to a certain rule in this sort of inquiry. Make sure usage of alphabetical order is proper.

For example, in one code, the word "PARKING" is written as "RYTIKLI." In that code, how will FLOWERS be written?

Explanation: Compare the first letter of PARKING to the first letter of RYTIKLI to see the pattern.

We observe that P is converted to R. R is two positions after P.

Now A is converted to Y. So we can conclude that A is two positions before Y.

So, PARKING is coded as +2 and -2 alphabets in an alternate manner.

Using the same logic, we can decode flowers

F – (+2) – H

L – (-2) – J, as so on

The correct answer is ‘HJQUHPQ’.

Substitution Coding

Names/words are substituted with different names/words in such questions. To arrive at the proper solution, we must carefully trace the substitution.

For example, what would be the name of the national bird if "parrot" is known as "Peacock," "Peacock" is known as "Swallow," "Swallow" is known as "Pigeon," and "Pigeon" is known as "Sparrow?"

Explanation: The national bird is the peacock, as we all know. However, ‘Peacock' is coded as ‘Swallow' in the supplied question. As a result, the right answer is ‘Swallow.'

Mixed Letter Coding

Three to four phrases in coded language are presented in this form of questions, and the code for a specific word is asked.

Any two phrases with a common term are chosen to answer such inquiries. That word will be referred to by the common code word. In the same way, all potential combinations of two phrases are chosen, and a common code is chosen.

In a certain code language,

1. ‘new banking system’ means ‘ss tp na.’

2. ‘officer in uniform’ means ‘or mu at.’

3. ‘new bank officer’ means ‘or bk na.’

4. ‘systems in bank’ means ‘bk at ss.’

• What is the code for ‘in’?

Explanation: In statements (2) and (4), the common code word is ‘in’, and the common code is ‘at’.

• What does the code ‘bk’ stand for?

Explanation: In statements (3) and (4), the common code word is ‘bk’, and the common word for that is ‘bank’.

Mixed Number Coding

Numbers are assigned to phrases in these types of inquiries. We can simply discover the answer by applying the same rule as in the previous situation. You must figure out the number code for each word and then arrive at the correct answer by selecting two phrases at a time.

Now let us solve an RBI grade B question.

In a certain code,

‘467’ means ‘leaves are green’,

‘485’ means ‘green is good’

‘639’ means ‘they are paying’.

What Is The Number Code For ‘leaves’?

Explanation: In statements 1 and 3, the common word is ‘green’, and the common number is ‘4’. So, ‘4’ is for ‘green’. Now, in statements 1 and 2, ‘are’ is common and ‘6’is common. So, ‘6’ stands for ‘are’.

In statement 1, only ‘leaves’ and ‘7’ are remaining; therefore ‘leaves’ corresponds to ‘7’.

Coding decoding reasoning includes coding questions. In such questions, students are usually given one word and its code, and they must find the code for the other word. The student must follow the same rationale that was used in the given words. This article provides a detailed insight on how to solve code language reasoning questions.
