# Basics of Coding-Decoding for Bank exams 2022

By Amrit Gouda|Updated : May 31st, 2022

Coding-decoding is one of the most widely asked topics in the Reasoning Section. Initially, there used to be different types of questions that were asked in Exam while nowadays as the level of Exams is increasing, new types of questions are added to the topic to make the overall paper challenging. So in this article, we are going to discuss the basics related to coding-decoding questions for Bank exams and each type of question from this topic so that it will be easy for you to understand the approach to solve those questions.

## Various types of Coding-decoding Asked in Bank Exams:

Kindly go through the below points to know various types of coding-decoding for Bank exams.

• Alphabets replaced by alphabets
• Alphabets replaced by symbol/number
• Words replaced by other words
• Digits given in tabular form

Let’s see various types of questions from coding-decoding for Bank exams one by one.

Type I: Sometimes the alphabets are replaced by some other alphabets in a given word and thus a coded word is obtained. The alphabet's replacement occurs according to some pattern. We have to observe that pattern and implement the same in the question asked.

Q-1. In a certain coding language, ‘WISDOM’ is written as ‘OMFQKU’ then how will ‘WATER’ be written in that language?

Solution:

After proper observation, we can see that:

W-2=U

I+2=K

S-2=Q

D+2=F

O-2=M

M+2=O

And now the coded alphabets are written in reverse order. i.e. OMFQKU

The same pattern will be used for finding the code for WATER

W-2=U

A+2=C

T-2=R

E+2=G

R-2=P

And now the coded alphabets are written in reverse order. i.e. PGRCU. So this is the code word for WATER.

Type II: Sometimes the alphabets in the word are directly replaced by some numbers or symbols. Generally, more than one example of such conversion is given which helps us in identifying the coded number/symbol sequence for the asked question.

Q-2. If ‘APPLE’ is coded as 14489 and ‘BANANA’ is coded as 315151 THEN how will ‘PALE’ be coded?

1. 1489
2. 1589
3. 5189
4. 4189
5. None of these

Solution:

In the given question, codes for APPLE and BANANA are given which enables us to get the code for each of the alphabet for the word ‘PALE’.

Note: We can find code for any word consisting of alphabets A, P, L, N, B, E.

A-1

P-4

L-8

E-9

B-3

N-5

Then ‘PALE’ will be coded as

P-4

A-1

L-8

E-9

So the answer is4189

Type III: Sometimes the coding is not at an alphabetical level while it is given directly for the words. i.e. one word is replaced by some other word. So we have to be careful while giving the answer because we have to write the code word as the answer for the one which is logically the answer.

Q-3. If ‘RED’ is called ‘WHITE’, ‘WHITE’ is called ‘BLUE’, ‘BLUE’ is called ‘GREEN’ and ‘GREEN’ is called ‘BLACK’, then what will be the color of blood?

1. RED
2. WHITE
3. GREEN
4. BLUE
5. BLACK

Solution:

In this example, logically the color of blood should be RED but we have to write the code word for the word RED which is WHITE. So WHITE is the answer to this question.

Type IV: (In trend) In some of the questions, three or four complete messages are given in the coded language and the code for a particular word is asked. To analyze such codes, any two messages bearing one or more common words are picked up so that we can extract the code words for the actual words. Proceeding similarly by picking up all possible combinations of two, the entire message can be analyzed and all the words can be decoded.

Directions: In a certain code language:

1. ‘money is not everything is written as ‘ma pa na ra’,
2. ‘everything is important is written as ‘na ma ta’,
3. ‘something is not right’ is written as ‘pa na ga sa’

Solution:

From the first two statements, we can infer that ‘everything is’ is written as ‘ma na’

From the first and third statements, we can infer that ‘is not’ is written as ‘pa na’

From these two conclusions, we can infer that

‘is’ is written as ‘na’

‘everything’ is written as ‘ma’

‘not’ is written as ‘pa’

Now we can look at the first statement and infer that

‘money’ is written as ‘ra’

Now we can look at the second statement and infer that

‘important’ is written as ‘ta’

‘Something right’ is written as ‘ga sa’

Q-4. What is the code for ‘important’ in the given coded language?

1. na
2. ma
3. ta
4. ra
5. None of these

Solution:

The answer to this question will be ‘ta’.

Q-5. What is the code for ‘not’ in the given coded language?

1. na
2. sa
3. ga
4. pa
5. None of these

Solution:

The answer to this question will be ‘pa’.

Q-6. What may be the possible code for ‘something is everything’?

1. ga na sa
2. ga pa sa
3. ga ma pa
4. sa ma na
5. None of these

Solution:

‘is’ is written as ‘na’

‘everything’ is written as ‘ma’

‘something’ is written as either ‘ga’or ‘sa’

So code for ‘something is everything’ can be either ‘na ma ga’ or ‘na ma sa’.

So option 4 is the correct answer.

Type V: Sometimes the code for various digits are given in a tabular form followed by some rules. The questions consist of a series of the digits (from the table) and the rules specify the modification in the digits while writing the code for the series given. We have to check all the rules while writing the code for the given series of digits.

Directions: In these questions, a group of digits is given followed by four combinations of letters and symbols numbered (1), (2), (3), and (4).

Digits are to be coded as per the scheme and conditions are given below. You have to find out which of the four combinations correctly represents the group of digits. The serial number of that combination is your answer. If none of the combinations is correct, your answer is (5) i.e., ‘None of these. Rules:

(i) If the first digit is odd and the last digit is even their codes are to be interchanged.

(ii) If the first, as well as the last digit, is even both are to be coded as *

(iii) If the first digit is even and the last digit is odd both are to be coded as the code for the last digit.

Q-7. what will be the code for ‘471536’?

1. *@\$H%*
2. R@\$H%U
3. U@\$H%U
4. R@\$H%R
5. None of these

Solution: The first, as well as last digit in ‘471536’, is even so condition (ii) follows which specifies that we will have to * as a code for both 4 and 6 while the code for other digits will be as per the given table. So option 1 is the correct answer.

Q-8. what will be the code for ‘697845’?

1. U#@ARU
2. U#@ARH
3. H#@ARH
4. R#@ARU
5. None of these Solution: The first digit in ‘697845’ is even while the last digit is odd so condition (iii) follows which specifies that we will have to code both 6 and 5 as per the code of 5 using table while the code for other digits will be as per the given table.

So option 3 is the correct answer.

Q-9. what will be the code for ‘590247’?

1. @#FTRH
2. H#FTR@
3. H#FTRH
4. @#FTR@
5. None of these

Solution: The first, as well as last digit in ‘590247’, is odd so no condition follows which means that the code for all the digits will be as per the given table. So option 2 is the correct answer.
