Coding and Decoding II- Reasoning Tricks to Solve Coding and Decoding Questions

Coding and decoding questions can fetch you 3-8 marks in IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams. Read on to master reasoning tricks that will help you solve these questions.

Coding and Decoding questions can be solved in just a few seconds if you can identify the reasoning tricks behind them. In the previous post of this series- ‘Coding and Decoding I- Reasoning Tricks for Decoding Codes in Bank & Govt Exams’, we discussed the various ways in which codes are written and the different reasoning tricks that are used to identify them. Before we move ahead to discuss higher order coding and decoding, you must glance through come commonly used reasoning tricks.

In this post, we will discuss some complex reasoning tricks that will help you to maximize your score in coding and decoding in Competetive Exams.

Set I – Coding and Decoding Problems form Jumbled Coding

One of the ways, in which coding and decoding is done is by jumbling the words. There are various reasoning tricks that are used for jumbling the letters in a given word. The jumbled code may put the words in a certain numerical order or an ascending or descending order based on their positions in the alphabetical series.
Problem 1: In a certain code ‘BEAN’ is written as ‘ABNE’ and ‘SALE’ is written as ‘LSEA’. How will ‘NEWS’ be written in this code?
Solution 1:
The minute we look at this coding and decoding question, there is one thing that strikes us immediately. The letters that have been used to write the code are the same as the letters in the actual word.

Now, the next thing to do is analyze the pattern and the set of reasoning tricks that will help 1
On closer examination of this code, we realize, that the letters of the word have been reorganized in an order-
B1 E 2A 3N4 à A3 B1 N4 E2
S1 A 2L 3E4 à L3 S1 E4 A2
So applying the same order to the given word we get-
So based on the order of the letters, we are able to decode this code.
Problem 2: In a certain code ‘TALENT’ is written as ‘AELNTT’. How will the word ‘SPRINT’ be written in this code?
Solution 2:
It is kind of obvious that the minute you look at this coding and decoding question, the logic used in the previous question resonates with you and you are tempted to use it in this coding-decoding question. But if you observe that will be very difficult to do in this case.
coding and decoding
Analyze closely, and you’ll see a pattern-
T1 A 2L 3 E4 N 5T6 à A1 E5 L12 N14 T20 T20
The letters in the word have been arranged in alphabetical order, in the same order as which they appear in the series of alphabets. So,
S1 P 2R 3 I4 N 5T6 à I9 N14 P16 R18 S19 T20
Arranging the letters in order we get our answer.

Set II – Coding and Decoding Problems form Complex Coding

This is a slightly complicated way of coding and decoding. All the reasoning tricks that we have discussed till now use one trick in coding and decoding. Often, more than one operation is performed on the word in coding and decoding, and when this is done multiple reasoning tricks are used. Such a way of coding and decoding is called complex coding.
Problem 1: In a certain code ‘JEALOUS’ is written as ‘BFKKTVP’. How will ‘HEARTEN’ be written in this code?
Solution 1:
The minute we look at this coding and decoding question, you may feel that something is not in place as none of the reasoning tricks discussed till now seem to be used here.
coding and decoding
This is an example of complex coding and decoding, where many operations have been performed on the same word.
The first step is to divide the word in 3 parts-
The next step is to reverse the set of letters in each of these parts-
In the 3rd step, we shift the letters- either one position forward or one position backwards-
coding and decoding
In the 1st part, we move the position by +1,  the position of the 2nd part is moved by -1 and finally, the position of the 3rd part is moved by +1. This gets us to the code –
We apply the same 3 steps to the word ‘HEARTEN’. Divide it in 3 parts, change their positions and then move them by +1 and -1 to reach the code-
coding and decoding
So we get the code for ‘HEARTEN’-

Set III – Coding and Decoding Problems form Chain Coding

This method of coding is actually the simplest and takes the least amount of time. In some ways, it is often also the trickiest because of the reasoning tricks involved in it. There are a series of codes in this because of which it is called chain coding.
Problem 1: In a certain code, ‘Green is Blue’, ‘Blue is Yellow’, ‘Yellow is Red’, ‘Red is Black’, ‘Black is White’ and ‘White is Brown’. What is the colour of blood according to the given code?
Solution 1:
Now this coding and decoding question is an absolute sitter if you approach it the right way, however if you get caught in the web of reasoning tricks, it may lead you to the wrong answer.
We know that ‘Blood’ is ‘Red’ in colour, so going by the codes that have been given here we can say that-
coding and decoding
Now some of you may take this a step further and say that since ‘red’ is ‘black’, ‘black’ is ‘white’ and ‘white’ is ‘brown’, so –
coding and decoding
But this is not the correct answer. The colour of blood is red and ‘red’ is coded as ‘black’.
The correct answer is ‘Black.’

Practice Questions using Different Reasoning Tricks for Coding and Decoding

Question 1: If in a certain language ‘CHAMPION’ is coded as ‘HCMAIPNO’, how can ‘NEGATIVE’ be coded in that code?
 Question 2: If ‘FULFNHW’ is the code for ‘CRICKET’, ‘EULGH’ will be coded as
1) PRIDE       2) BRIDE       3) BLADE      4) BLIND       5) None of these
