Importance of Coding-Decoding for Bank Exams 2022

Coding-decoding is an important chapter in the Reasoning Syllabus of Bank exams. Kindly go through the below points to understand the importance of coding-decoding questions for bank exams.

  • You will get 4-5 questions in both Prelims and Mains phase.
  • The concept is really easy to learn.
  • With conceptual clarity and proper practice, you can easily score full marks in minimum time.
  • This will improve your chance of scoring high marks on the exam.

How to Solve Coding-Decoding Questions Based on New Pattern?

Now we shall discuss how to solve coding decoding questions for IBPS Bank po and clerk exams by solving some examples. We will discuss the strategy and tips as per the question.

Example(1-3) Study the following information carefully and answer the questions given below:
In a certain code language
‘given  time  simple  plan’ is written as ‘@E4  &N4  %N5  #E6’
‘tired  solution  plant  great’ is written as ‘#N8  @D5  %T5  &T5’
‘sick  point  good  turn’ is written as ‘#K4  %D4  @N4  &T5’
‘garden  sister  phone  team’ is written as ‘&E5  #R6  %N6  @M4’

1. Which of the following code for ‘translate’?
A. @E8
B. @E9
C. #E8
D. #T8
E. #T9

2. Which of the following code for ‘plan’?
A. %N5
B. @E4
C. &N4
D. #E6
E. None of these

3. In the given code language, what does the code ‘%D4’?
A. point
B. turn
C. sick
D. good
E. None of these

How to Solve this Coding-Decoding:
Here are some points to keep in mind when we solve these kinds of questions-

  • As we all know there is always a concept behind this which we need to find out. Looking at the questions, we can see that in all the steps, all 4 words start with the same alphabet. They all start with- G, T, S, and P, and their code word also start with the same symbol in each step- @, %, &, and #. So we just have to find which of the first alphabet represents the particular symbol.
  • Now we can see that their code words end with digits. When we look at those digits, they are the total number of letters for each word.
  • Now we can see the middle codeword is the last letter of that particular word.

So, this was the pattern. Now we solve the questions. 

Answer 1: B 

Solution:

We have to ‘translate’ code. As we can see that this word is not given in any steps but so we can solve it.
Step I: first we will count the letters of that word that is 9, then we put the digit 9 at the right end.
Step II: we will put the last letter of that word then it will like- E9
Step III: at the last step ‘t’ is coded for ‘@’(the first letter of each word is coded by a specific symbol like here ‘t’ is coded for ‘@’. We can find the first coded symbol by looking at the other given words. The answer will be - @E9

Answer 2: C

Solution:

We have to find the code of the ‘plan’. Now the same steps follow. A plan is given in the first step. The total count of letters is 4 and the last letter is N and ‘p’ is coded as & So, the final answer will be- &N4

Answer 3: D

Solution: 

We have given ‘%D4’ and we have to find it's a word.  So we can say that the number of letters will be 4 and the last digit will be D and ‘%’ is represented by G. so in the 3rd step, we can find this word, the final answer will be Good

Example (4-8): Consider the following statements and the questions that follow. We will analyze this problem in detail after that.

In a certain code language
login BYJU'S Exam Prep and scroll” is written as “&3d  @6l  *5n  %7p
scroll for sbi exam” is written as  “@6l  @3i  $3r  #4m
study exam related notes” is written as “#4m  @5y  !7d  =5s
read notes get job” is written as “+3b  !4d  =5s  %3t

4. Which of the following code is for gradeup?
A. @6l
B. &3d
C. %7p
D. *5n
E. None of these

5. According to the above information, code !7d is used for?
A. study
B. exam
C. related
D. notes
E. read

6. What will be the code for “exam gradeup sbi job”?
A.  +3b #4m %7p =5s
B. %3t @6l @5y !7d
C. %7p +3b #4m @3i
D. !4d $3r @6l &3d
E. None of these

7. According to the coding, what will be the code for banking?
A. @7g
B. &7h
C. $7t
D. one of these
E. can’t say

8. What will be the code for probationary?
A. $12y
B. %11n
C. ^12y
D. *13t
E. #12p

Let’s analyze the above information in detail.
Firstly, read the statements and their given codes properly. You can see that there are some words that are common in given statements like scroll, exam, notes, and in the codes as well - @6l, #4m, =5s. In codes, there are also some special characters that are repeated in different sentences like @ is repeated in all three statements.

From statements 1 and statement 2
“login gradeup and scroll” is written as “&3d  @6l  *5n  %7p”
scroll for sbi exam” is written as  “@6l  @3i  $3r  #4m”

i.e. scroll is common in both statements, so we look for the common code in these two statements, which is @6I.

Similarly, From statements 2 and 3
“scroll for sbi exam” is written as  “@6l  @3i  $3r  #4m
“study exam related notes” is written as “#4m  @5y  !7d  =5s”

From statements 3 and 4
“study exam related notes” is written as “#4m  @5y  !7d  =5s
“read notes get job” is written as “+3b  !4d  =5s  %3t”

Now scroll = @6l, exam = #4m, notes = =5s

Now, let us understand how the words are coded.

1. The last letter of the code is the alphabet and it is the same as the last letter of the given word.
2. Given a number in coding is the total letter of words. So, it is clear that in codes, the number represents the total letter of words and the code letter is the last letter of the word
3. But special characters are different for all words. Now our next step is to decode them.

We can see that in statement 2, @ has been used two times in coding and s is also the first letter of two words (i.e scroll and sbi). To become sure we can check another word like gradeup and get, both have the same % special characters. Similarly, related and read have the same (!) special characters.

l

g

a

s

f

e

r

n

j

*

%

&

@

$

#

!

=

+

Hence code of the word is given as the code of the first letter, the total no. of letters in the word, and the last letter of the word.

IMPORTANT: In this question, the short clue is the total no. of letters in the word is given as it is in code.

As per this information,

Answer 4: (C)As we can see in word BYJU'S Exam Prep
first letter g = %
total letter = 7
last letter = p
So, the code is %7p

Answer 5: (C) ! is code for r, 7 total letters, and d is the last letterSo we can say that related is the word.

Answer 6: (C) Exam = #4m, BYJU'S Exam Prep = %7p, sbi = @3i, job = +3b. Hence answer is C. 

Answer 7:(E) can’t say. Because we don’t have a code for the first letter “b” of banking.  All given special character in answer code are @=s, $=f and & = a.

Answer 8:(C) In this question our approach will be the options elimination method. As the first letter of probationary is ‘p’ and we don’t have any code for p. But in options A, B, D, and E, the code of the first letter is the same as mentioned in the above table. So options A, B, D, and E are eliminated and our answer will be C. This was a new pattern question that was introduced in last year’s exams.

Let us now have a look at what other sorts of pattern changes you can face in Coding-Decoding.

Example (9-12): Consider the following statements and the questions that follow. We will analyze this problem in detail after that.

In a certain code language
login BYJU'S Exam Prep and check” is coded as “$4e %4g #2n @6d
reads article study there” is coded as “@6i #4u $4e %4a
comment about yours doubt” is coded as “$4u @4o %6m #4u
get clear exams enjoy” is coded as “@4e #4a $4j %2e

9. What is the code for the exams?
A. @4e
B. #4a
C. $4j
D. %2e
E. None of these

10. What is the code for the study?
A. $4e
B. #4u
C. %4a
D. @6i
E. None of these

11. What is the code for about?
A. %6m
B. $4u
C. @4o
D. #4u
E. None of these

12. If we code “study BYJU'S Exam Prep clear exams” as per the above coding method, what will be the code?
A. $6u %4d #4a @4e
B. %4u #4e @6d $4a
C. @4e $6d #6e %4a
D. #6d @4u @4e %4m
E. None of these

Let’s analyze this problem in detail -
Again, read the statements and given codes properly first. In this, we can see that all (#$%@) are used in every statement. Clearly, they cannot represent any particular letter because the letters are changing in different statements.
Next, if we check the number given in the coding of the first statement - 4,4,2 and 6 are used and letters in a word are 5,7,3 and 5. So, the numbering given in the code is 1 less than the number of letters given in the word. But we cannot comment on the English letter given in the code.
#2n = and, @6d = BYJU'S Exam Prep, but there is a confusion between $4e and %4g, both login and check are 5 letters words.

From 2nd statement coding, we can see that only code @6i has a different number (i.e. 6), the remaining codes have the number 4. The article is the only word that has 7 letters and we have derived that numbering in coding is 1 less than the number of letters in the word. So, article = @6i

Now we will try to derive the English letter which is given in the coding statement.
#2n = and, @6d = Gradeup, @6i = article, hence letter in coding is the middle letter of the word.
Next, Both BYJU'S Exam Prep and article are at serial number 2 in the statement and both have @ coding. AND is at serial no.3 in the statement, so # = 3
Hence we have decided on this coding.

So, we can say that,
numbers in code = total no. of the letter in a word – 1
Special characters are serial no. of words, % = 1, @ = 2, # = 3 and $ = 4
English letter in code is the middle letter of the word.

Important: If you have seen it carefully, you can check that all numbers in codes are even and the letters of words in the statement are odd. So we can say that there is some addition or subtraction in the number of letters of a word.

Answer 9 (B): exams are in statement 4 at third place, so for third place code is #, no. of letters in exams is 5, so numerical code is (5-1) = 4 and the middle letter of the word is a. So the code for it is #4a.

Answer 10 (B): The study is in statement 3 at third place, so for third place code is #; no. of letters are 5, so numerical code is (5-1) = 4 and the middle letter of the word is u. So the code for it is #4u.

Answer 11 (C): about is at second place in statement 3, so for second place code is @, no. of; letters are 5 so the numerical code is (5-1) = 4 and the middle letter of the word is. So the code for it is @4o.

Answer 12 (B): This is a different question, in which you have to code according to the above coding method.

study is at first place in the statement, so the code is %4u.
Gradeup is at second place in the statement, so the code is @6d.
clear is at third place in the statement, so the code is #4e.
exams are at fourth place, so the code is $4a.

This is all about the importance of coding-decoding questions for bank exams. Also, we have discussed a few examples to show how to solve coding-decoding questions.
