Coding or coding is a method of one type of instructions in which information is secretly exchanged, i.e. one person sends a dialogue to another person, the other receives it, only it receives only the coder decoder. I do not know anything, that is, there is no definite rule. In such queries, a code is decoded, others have to decode on this basis. For such questions, all English letters have to remember the number and their opposite number.
It contains a few words / letters / numbers that do not display their reality but display something else. It is made up of certain rules, which is to check the law and use the same language.

Coding: Coding is the method of making any meaningful word change in meaningless words / letters / digits according to a particular rule.
Eg: SANTOSH -> TZMGLHS / TBOUPTI / RZMSNRG or others

Decoding: Decoding the meaning of a meaningless word for a meaningless word in a meaningless word is called decoding.
Eg: WFITVHS -> DURGESH


(A) Remember the serial value of all the letters of the English alphabet. The systematic order from A to Z is called the English alphabet. There are 26 letters in the English alphabet. In which all the values of the letters are different

A – 1

B – 2

C – 3

D – 4

E – 5

F – 6

G – 7

H – 8

I – 9

J – 10

K – 11

L – 12

M – 13

N – 14

O – 15

P – 16

Q – 17

R – 18

S – 19

T – 20

U – 21

V – 22

W – 23

X – 24

Y – 25

Z – 26

With the help of the word ‘EJOTY‘ the value of the letters of the entire English alphabet can be remembered. The letters of the word ‘EJOTY‘ are numbered according to the alphabet in the English alphabet.
E-5
J-10
O-15
T-20
Y – 25

Example 1: What is the 22nd letter from your left in the English alphabet?
Solution: Since EJOTY we know that
T = 20
22 -> T + 2 = V

(B) When solving sign language questions, the letter needs to be opposite to each letter, which is considered necessary to remember.
Opposite letter

A – Z

B – Y

C – X

D – W

E – V

H – 8

F – U

G – T

H – S

I – R

J – Q

K – P

L – O

M – N

Unlike each letter in the English alphabet, the letter can be known by the Addition Method.
If there are any two letters in the English alphabet with the sum of the alphabet having the sum of 27, then the two letters will be mutually opposite to each other.
Eg: A = 1, Z = 26
A + Z = 1 + 26 = 27
Thus A and Z are the opposite letters of each other.

Example 1 . What will be the opposite letter of letter S in the English alphabet?
Solution: S = 19
27 = 19 + 8
8 = H therefore the letter -> H

Unlike each letter in the English alphabet, the letter can be known by the subtraction method.
The reduction of the value of any letter in the English alphabet from ’27 ‘, the remaining letter remains the opposite letter of the lowercase letter.

Example 2. What would be the letters of the letters of the English alphabet P and N?
Solution: P = 16. The opposite letter of P = 27 – 16 = 11 -> K
Similarly, the opposite letter N = 14: N = 27 – 14 = 13 -> M

 

TYPE 1

Alphabetical coding: Understand the pattern of the question based on which pattern the sign is following. Depending on the questions asked in the exam, there may be following patterns.

Form I: Characters given in the sign proceed from their location (Forward Sequence Pattern)

Example: In an indicative language, HAND is called IBOE, then what will SILK be called?
Solution: TJML in I for H, B for N, O for D, E for D, i.e. each letter has moved one place from its position. Hence TUML will be for SILK.

 

Form II: The letters in the sign can be reversed from their location (Backward Sequence Pattern)

Example: In a sign language if WRITE is called VOHSD, what will MIGHT be called?
Solution: LHFGS In this question, the letter of the sign is the letter behind its position, for V for V, for O for R, H for T, S for T, D similar to E, similar to the question word Will be written by the letters behind it.

 

Form III: Two or more than two or more than your location (Skipped Sequence Pattern)

Example 1. In a sign language if CHAIR is written EJCKT, how will LIGHT be written in the same sign language?
Solution: NKlJV
The letter of the word given in the sign of this question is moving forward, leaving the letter E (D is omitted), for the H, J (I is omitted) NKIJV will answer after following the same rule in getting the signal.

 

Form IV: By Changing Places

Example 1. In a sign language if the MOTHERS is written in SREHTOM, how will BROUGHT be written in the same sign language?
Solved: THGUORB
The characters in the given code are written in reverse order.

Examples 2. In a sign language if written to BREAKTHROUGH RBAETKRHUOHG, how would the DISTRIBUTION be written in the same sign language?
Solution: IDTSIRUBITNO
Each of the two letters has been changed in the sign of the letters given in it.

 

Form V: By the opposite letter of the words used in the word (By Opposite Letter of the Letters Used in the Word)

Example 2. In a sign language, if KING is written PRMT, how will RAIN be written?
Solution: IZRM
Each letter is coded as the letter of the opposite sequence. Like A = Z, B = Y, C = X, D = W, M = N etc.

 

Form VI: Coding by Analogy

Example : in a sign language, if BLADE will be written as SPTFA, then what will be the code of BALE on that basis?

Solution: STPA
In the given question, any of the above patterns have not been followed. The questions of the words in the words of the word are the codes of the words in the given word.

 

TYPE 2

Number coding: Such questions are given as code numbers in the form of letters. These numbers may or may not be affiliated in alphabetical order of letters.

Form I: Letters are denoted by digits (letters of Word are denoted by Digits)
Example 1. In a sign language if CHAIR is written 53269 and EAR 729, then how will HEAR be written?

Solution: 3729

In this type of question, make sure to check the code of common characters in the same way, like the codes of A and R are both words 2 and 9.

Example 2. If RIPSLE is written 613082 and WIFE to 4192, how would PEWSL be written in the same way?

Solution: 32408

 

Form II: using the mathematical operations by using any arithmetic method

Example 1. If CAT is written 24 and SAD 24, what will be the SHE?
Solution: CAT – 3 + 1 + 20 = 24
SAD – 19 + 1 + 4 = 24
SHE – 19 + 8 + 5 = 32

Example 2. If DEEP is written 60 and RABIT 100, then what would HAIR be written?
Solution: DEEP – 4 + 5 + 5 + 16 = 30-> 30×2 = 60
RABIT- »18 + 1 + 2 + 9 + 20 = 50-> 50×2 = 100
So HAIR – »8 + 1 + 9 + 18 = 36 -» 36 x 2 = 72

Example 3: If 123 is written 36 and 225 is 81, then what will be written as 331
Solution: 123 -> 1 + 2 + 3 = 6 -> 62 = 36
225 -> 2 + 2 + 5 = 9 -> 92 = 81
So 331-> 3 + 3 + 1 = 7-> 72 = 49

 

TYPE 3

Word Coding OR Word Substitution: In this type of question, the word is used as a sign instead of one word.
Example 1. If the cloud is called ‘white’, ‘white’ to ‘wind’, ‘air’ to ‘blue’, ‘blue’ water, water is power, tell where the bird will fly?
Solution: Blue
Usually the birds fly in the air and the air is called blue. So the answer will be blue.

 

TYPE 4

Mixed Coding in this sentence is indicated from one sentence of three or four words to another, and there are three such sentences, and a single word is asked.
Example 1: ‘NEE TIN FU’ in any sign language means ‘HOW ARE YOU’ and ‘NEE TIN SE’ WHERE ARE YOU, what will be the code for ‘WHERE’?
Solution: In the kind of question given earlier in this question, the indications of common words are seen first.
Such as – nee tin fu – how are you
nee tin se-where are you
In both of these sentences ‘nee’ and ‘tin’ and ‘are are’ you are in common, in the second sentence ‘where’ and ‘se’ in the code sentence is being saved, so the code of ‘where’ will be ‘se’.

 

TYPE 5

Symbol Coding Such codes are encoded as symbols.
Example 1. In a particular code, write $ SOLE to # 54 and DIME to 3% 7 #. How MODES will be written in that code?
(a) 75 # 3S (b) 753 # $ (c) 753% $ (d) 75% 3S (e) None of these
Solution: (b) The way,
S – $
O-5
L-4
E – #
And
D-3
I- #
M-7
E-#
Similarly, (together with both words MODES was created)
M-7
O-5
D-3
E-#
S-$

 

TYPE 6

Rearrangement Coding: Different words given under such questions are rearranged in different order.

Example 1: In a special code, ‘in what way is it justifiable to Sacrifice an animal’ is written as ‘way an it to justifiable in the sacrifice is what animal’. How would “it fell on the able shoulders of Sankara to clear” in that code?
(a) to a capable of it
(b) on to able of shoulders
(c) on to of able shoulders
(d) On to able of shoulders it Sankara fell the clear –
(e) None of the above
Solution: (b) The way,
In what way is it justified to sacrifice an animal 1 2 3 4 5 6 7 8 9 10

=> Way an it to justify in Sacrifice is what animal 3 9 5 7 6 1 8 4 2 10

Similarly, -> it fell on the shoulder of Sankara to clear 1 2 3 4. 5 6 7 8 9 10
on to able of shoulders sankara the fall clear 3 9 5 7 6 1 8 4 2 10

 

TYPE 7

Condition Based Coding: There are different numbers / letters / symbols given below in the group / number of different characters under such questions under which some conditions are given below which apply differently in the given questions. Happens.
=> Instructions Below are a group of letters in each question and followed by four groups of points (A), (B), (C) and (D). Based on the given number code and the below given conditions, you have to find out which group of digits represents the group of letters and accordingly the answer is visible. If any group of digits does not represent the letter given in the question, give the answer (E) that means none of them /
Letter P A J L M E R U K.
Number code 2 5 8 6 1 3 9 4 7
Terms:
(i) If the first letter is the consonant and the last letter tone, then both will be coded as *.
(ii) If the first letter is the vowel and the last letter consonant, both will be coded as $.

Example 1: R K P J A
(A) $ 7268
(B) ★ 7268 ★
(c) * 2768 ★
(d) 972685
(e) None of these
Solution: (b) R K P I J A  -> ★ 7268 ★

Example 2: M. JK P R K
(a) 187279
(b) 178297
(c) 287179
(d) ★ 8729 ★
(e) None of these
Solution: (e) MJKPRK – 1 8 7 7 9 7
