What is Coded Reasoning

This post on Coding, Decoding, and Reasoning will provide you with some strategies and suggestions, as well as examples, to make you feel better and easier while you are solving, which will make it easier for you to pass the exam.

Within the realm of Reasoning, Coding, Decoding, and Reasoning are three of the most difficult subject areas to cover. This portion is one of the most typical sections that is included in all of the main competitive examinations that are specifically designed for the purposes of higher education and employment. Many applicants believe that the questions involving coding-decoding and reasoning are difficult to complete; as a result, they avoid tackling certain scoring questions, which causes them to miss out on some simple and straightforward points.

What Exactly are the Terms “Coding,” “Decoding,” and “Reasoning”?

Because it is possible that each of these three concepts is somewhat difficult to grasp, let us first become familiar with each of them by examining their definitions.

The segment on logical thinking known as coding is used to encode words and numbers according to predetermined patterns or codes by making use of a set of predetermined guidelines and policies. Decrypting the patterns into their original forms from the forms that have been given is accomplished through the process of decoding.

Examples of Different Types of Coding and Decoding

The types can be broken down into a few different categories, but the ones that are going to be covered in this tutorial are the ones that have a significant influence right now in terms of coding, decoding, and reasoning.

Letter Coding

The term “letter coding” refers to a method of coding in which the letters are substituted with other letters.

Consider the following illustration of letter coding:

If “KMLICW” is the code for MONKEY, then what should the code be for ORANGE?

Remembering that each letter of the alphabet corresponds to a certain number is necessary in order to find solutions to problems of this nature.

Therefore, in response to your query,decoding and reasoning number coding. 

The secret word for currency is MONKEY.

M can be decoded as the number 13.

O has the numerical value of 15.

N can be decoded as the number 14.

The numerical value of K is 11.

E is represented by the number 5.

Y can be decoded as 25.

In a similar fashion, “KMLICW” can be decoded as

The numerical value of K is 11.

M can be decoded as the number 13.

The number 12 represents the letter L.

I is represented by the number 9.

The value 3 represents the letter C in binary.

W can be represented by the number 23

If you pay attention to both the supplied word and, you will notice that the code is generated by subtracting 2 from each alphabet.

Therefore, in the same manner, the same number ought to be decreased in order to code “ORANGE.”

So you code “ORANGE” as:

O has the numerical value of 15.

R has the numerical value 18

The value of A is a 1

N can be decoded as the number 14.

The numerical value of G is 7.

E is represented by the number 5.

In the same manner, it resulted in a reduction of two letters for each alphabet.

The whole answer for Orange would look like this: 13, 16, 25, 12, 5, 3.

And the term should be encoded with the “MPYLEC” prefix.

The Coding of Numbers

During the Number Coding portion of the reasoning ability test, the candidate will be required to observe and deduce the secret code buried inside two or more sets of numbers. After the candidate has determined the parent code, the candidate will be required to use this code to produce more numbers.

If the code for “HOUSE” is 35842, and the code for “LEMON” is 12659, then what is the code for “HELEN”?

Because the code for each letter is already provided in the question itself, there is no longer any need to utilise fixed codes for the letters. Explanation:

HELEN

Now, in order to solve the problem, you need to give the number of each letter. If you look closely at the two words, you’ll notice that some of the letters are duplicated; therefore, there is no need to write those letters twice.

Now, translate the letters into a code.

The number 3 denotes the letter H.

O is represented by the number 5.

U is represented by the number 8.

The numerical value of S is 4.

The numerical value for “E” is “2.”

The number 1 represents the letter L in binary.

M can be decoded as the number 6.

The numerical value for “N” is 9.

With these codes, the name “HELEN” is represented as the numbers 3,2,1,2,9.

Coding using Substitutions

In the process of replacement coding, specific things are designated with code names. Following that, a question is posed in the same format in order to solve the answer.

Now, let’s have a look at the example so that everything is crystal clear.

You already possess

If “white” is called “red,” “red” is named “blue,” “blue” is called “green,” “green” is called “yellow,” and “yellow” is called “black,” then what colour is blood, given that “white” is called “red” and “red” is called “blue”?

Explanation: It’s well known that blood has a crimson colour. If you look at the question that came before this one, you’ll see that it says that blue is called red and that red is called white.

If one were to use the method of substitution to determine the colour of blood, one would find that the colour is blue.

Coding Using a Mixture of Letters

In this kind of inquiry, three or four full messages will be supplied in the coded language, and the question will ask for the code for a certain word. to decipher such codes and determine whether or not any two communications sharing a word were chosen for examination. That word is going to serve as the standard code word.

Conclusion

Therefore we can finally conclude that the purpose of the Reasoning section is to determine a candidate’s level of logical aptitude or ability. You should now have a crystal clear idea of why you are learning coding, decoding, and reasoning in this coding, decoding, and reasoning lesson because you have been provided with that information.

Ans. To begin writing in code, you must first compose the message that you want to transmit in reverse. Then, between each of the letters in your first message, place a letter and a number in between each of the letters. To everyone else, your communication will appear to be a jumbled collection of letters, numbers, and other symbols.

Ans. A clever strategy for handling problems involving “Coding and Decoding”

Take note of any letters or numbers that are provided in the question.

Investigate whether there is a pattern or a sequence that it follows. …

Find the pattern that the provided arrangement of letters, numbers, and words follows, and write it down.

Ans. In all examinations that measure aptitude, the CODING-DECODING section is a significant component of the LOGICAL REASONING section. The practice of encrypting a word or a number in a certain code or pattern according to a predetermined set of guidelines is referred to as coding. Decoding is the process of reassembling the pattern into its initial shape using the codes that have been provided.

A posterior probability, in Bayesian records, is the revised or updated probability of an event happening after taking into account new records. The posterior probability is calculated by updating the prior probability by using Bayes’ theorem. In statistical phrases, the posterior probability is the probability of event A taking place given that event B has taken place.
