Coding-decoding is an important topic from the perspective of the upcoming banking exams which will be held in the coming days. To help you prepare & revise the concept of coding-decoding, we have come up with this useful PDF which also has questions for practice. If you have missed preparing coding-decoding topic, this PDF is perfect for you. Download it and refresh this concept. Talking about the importance of coding-decoding, it has been asked a number of times in the past banking exams. Be it IBPS Clerk, SBI PO, RRB PO, RRB Clerk or any other similar exam, And it’s considered an easy-moderate topic if you understand the concept behind it and practice enough questions. It’s likely that coding-decoding questions will be asked in a number of exams this year as well. So why not understand & practice this concept well enough to answer the questions Let’s get started:
In these questions, you need to understand the methodology/ logic behind coding the given information in the question and answer the question accordingly. The quickly you can understand the logic and are able to accurately implement the logic in another set of information, the better marks you can score. To start with, there can be 4 types of coding-decoding questions:
Here alphabets are coded in a specific pattern. Let’s understand it better with the help of an example:
In a certain code, ABSORB is written as LIYZYH. How will be BRACES written in the same code?
When the letters of the alphabet are counted in normal order (starting from A) and in reverse order (starting from Z), then A and Z have the same ranks (1), B and Y have the same ranks (2), C and X have the same ranks (3), and so on. The below chart will be helpful in solving these kinds of coding:
A | Z |
B | Y |
C | X |
D | W |
E | V |
F | U |
G | T |
H | S |
I | R |
J | Q |
K | P |
L | O |
M | N |
N | M |
O | L |
P | K |
Q | J |
R | I |
S | H |
T | G |
U | F |
V | E |
W | D |
X | C |
Y | B |
Z | A |
In this coding, all the letters are not coded serially. The word is first split into two, i.e., ABS and ORB and their positions are interchanged and then they are coded:
ABS ORB => ORB ABS => LIY ZYH
Similarly BRA CES => CES BRA => XVH YIZ
So XVHYIZ is the correct answer.
In numerical coding or symbol coding, instead of alphabets, numbers or symbols are used. The logic of coding can be found in the question itself. Let’s check an example.
FACES has been coded as 2)^18 and TEN is coded as +1$ in a language. How will be CEAT coded in the same language?
In the above example, we can see that random numbers/ symbols have been assigned to different letters. We can sort it out as per the below distribution:
F 2
A )
C ^
E 1
S 8
T +
N $
Likewise, CEAT will be coded as ^1)+.
Here the words in a sentence are substituted by other elements. These elements can be other letters/ words/ numbers/ symbols. Check the below example to help it better:
Answer the questions on the basis of the following information.
In a certain code language,
(i) ‘word that spell magic’ is coded as ‘ku tu pu lu’.
(ii) ‘that in the spell’ is coded as ‘mu nu ku tu’.
(iii) ‘word that air without’ is coded as ‘Iu ju ku fu’.
(iv) ‘air the saying any’ is coded as ‘nu du su fu’
Which among the following may be the code for ‘that any’?
A. ku ju
B. ku lu
C. du su
D. ku du
E. fu tu
With the help of the given information, we can easily conclude the below codes:
word | lu |
that | ku |
is | tu |
magic | pu |
in | mu |
the | nu |
air | fu |
without | ju |
saying | du/su |
any | su/du |
spel | tu |
So option D. is correct.
Now that we have got an idea about coding-decoding questions after observing the above examples, let’s have a look at some tips & shortcuts of coding-decoding which will be pretty useful in answering these questions.
Alpahabet | Position (Forward) | Alpahabet | Position (Backward) |
E | 5 | V | 5 |
J | 10 | Q | 10 |
O | 15 | L | 15 |
T | 20 | G | 20 |
Y | 25 | B | 25 |
After understanding the concept and going through the examples and tips, it’s time to roll up one’s sleeves and get into the practicing mode. We are providing you the below questions which you can practice. For answers & detailed explanation, we encourage you to download the free PDF.
