Letter Coding: The letter coding-decoding is one of the most important topics of logical reasoning. The English alphabet plays an important role in this topic as the whole topic revolves around the alphabet. The various types of questions of letter coding are asked in almost every competitive and entrance exam. The exams are SSC, RRB, PCS, UPSC, KMAT, CUET, CLAT, VITEEE, MAT, JIPMAT exams etc in which these questions are asked. This article is the most important for the candidates who are preparing for any government or entrance exam.
In this article, we will cover the concept of letter coding, how to solve letter coding questions, letter coding examples and explanations, letter coding reasoning tips and tricks, letter coding tricks and techniques, letter coding with numbers, letter coding reasoning for competitive exams and practice letter coding reasoning questions.

What is Letter Coding?

Letter coding reasoning is defined as the coding of the letters by the letters themselves, numbers, symbols etc by following some specific rules or patterns. The topic letter coding reasoning is based on encoding a letter, a number, or a word. Coding letters, numbers, or words is based on various rules and patterns. The candidates have to decode the correct pattern for the coded letters, numbers or words to solve the questions.

Types of Letter Coding

There are five types of letter coding reasoning which are as follows:

  1. Direct Letter Coding/Letter to Letter Coding

  2. Letter to Number Coding

  3. Letter to Symbol, Number Coding

  4. Chinese Coding

  5. Matrix Coding

Now let’s discuss each type in detail:

1) Direct Letter Coding/Letter to Letter Coding

In this type of coding question, the letters are directly coded as letters with the help of different operations on the positional value of the letters, such as addition, subtraction, etc. Let’s understand this with the help of an example.

Example:
Directions: In a code language, TORCH is written as UNPSDI, and BEST is written as CDFTU. How will MARKS be written in that language?

  1. OZBSMT

  2. NZCSLT

  3. NABSLU

  4. NZBSLT

Hint: The vowel is coded with its previous and next letter and consonants are coded by its next letter as per the alphabetical series.

Solution

Code the vowel with its previous and next letter in the alphabetical series while consonants are coded by their next letter.

For TORCH, to obtain the required code –

1732182187526

Thus, TORCH is coded as UNPSDI.

For BEST –

1732182187723

Thus, BEST is coded as CDFTU.

Similarly, for MARKS –

1732182187895

Thus, MARKS is coded as NZBSLT. Hence, the fourth option is correct.

2) Letter to Number Coding

In this type of coding question, the letters of the given words are coded as numbers with the help of different operations on the place value of the letters, such as addition, subtraction, etc. Let’s understand this with the help of an example.

Example:
Directions: In a certain language, the word CLOCK is written as 4 – 13 – 17 – 4 – 12. How will you write PHONE in the same language?

1) 17 – 10 – 16 – 15 – 6

2) 17 – 9 – 16 – 17 – 6

3) 17 – 9 – 17 – 15 – 6

4) 16 – 9 – 15 – 16 – 5

Hint: Determine the code by using the position values of the letters of a given word.

Solution

Write the position values of the letters of CLOCK, and then add 2 to the position value of O, and add 1 to the position values of the remaining letters to obtain the required code –

C→3; L→12; O→15; C→3; K→11

Now, add 2 to the position value of O, and add 1 to the position values of the remaining letters –

C→3 + 1 = 4; L→12 + 1 = 13; O→15 + 2 = 17; C→3 + 1 = 4; K→11 + 1 = 12

Thus, CLOCK is coded as 4 – 13 – 17 – 4 – 12.

Similarly, follow the same pattern for PHONE –

P→16; H→8; O→15; N→14; E→5

Now, add 2 to the position value of O, and add 1 to the position values of the remaining letters –

P→16 + 1 = 17; H→8 + 1 = 9; O→15 + 2 = 17; N→14 + 1 = 15; E→5 + 1 = 6

So, PHONE is coded as 17 – 9 – 17 – 15 – 6. Hence, the third option is correct.

3) Letter to Symbol, Number Coding

In this type of coding question, the letters of the given words are coded as different types of symbols such @, #, $, %, *, & etc or with numbers. Let’s understand this with the help of an example.

Example:
Directions: If PENCIL is coded as ?@.=;7 and PAPER is coded as ?9?@5, how will you code CLIP?

Solution: Each letter of the word PENCIL is coded with the equivalent symbols and numbers given in the code –

P→?, E→@, N→., C→=, I→;, L→7

Thus, PENCIL is coded as ?@.=;7.

And, PAPER is coded as ?9?@ 5 –

P→?, A→9, P→?, E→@, R→5

All the letters of CLIP are given in PENCIL, therefore, the code for CLIP is→

C →=, L→7, I→;, P→?

So, CLIP is coded as =7;?.

4) Matrix Coding

This type of coding question is based on the matrices. In this type of coding, two matrices are given in the question. In the given matrices, the letters are coded as certain numbers. One letter can have more than one code. Let’s understand this with the help of an example.

Example:
Directions: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. A can be represented by 03,10, etc., and P can be represented by 55, 67, etc. Similarly, you have to identify the set for the word REST.

A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. A can be represented by 03,10, etc., and P can be represented by 55, 67, etc. Similarly, you have to identify the set for the word REST

Matrix

A) 96, 33, 44, 87
B) 58, 21, 85, 75
C) 89, 40, 31, 56
D) 77, 10, 5, 68

Here, from the matrices (Matrix 1 and Matrix 2) we get the numbers that represent the letters of the word REST –

R→58, 65, 77, 89, 96

E→02, 14, 21, 33, 40

S→59, 66, 78, 85, 97

T→56, 68, 75, 87, 99

Therefore, on comparing these numbers with the given alternatives, we get that the word REST is represented by the numbers 58, 21, 85, and 75. Hence, the second option is correct.

5) Chinese Coding

In this type of coding question, a set of a few statements consisting of words, numbers, letters, or symbols in different order are coded as words, symbols, letters, or numbers. The candidates have to find the codes of the given words in the statement by identifying the common words in different statements. The code for the common words will be the same in all the statements. Let’s understand this with the help of an example.

Example:
Directions: In a certain code language, heat is waves is coded as 76@, and waves are dramatic not is coded as 34%7. What can be the code for heat in that language?

1) %

2) 4

3) @

4) 3

Hint: Compare the statements and determine the common words and code.

Solution

From statement 1, we have heat which is only in statement 1 and either 6 or @ is the code for heat.

In options, as we have only @, we can choose the given option.

So, heat is coded as @. Hence, the third option is correct.

How to Solve the Questions of Letter Coding?

To solve the letter coding reasoning questions candidates can follow the below points:

1) Firstly, to master the topic letter coding reasoning or to solve the questions quickly candidates must learn the positional values of the letters in both forward and backward directions and the candidates must know numbers such as odd, even, prime numbers and multiples of numbers.

2) There are a total of 26 letters in the English alphabet of which 5 are vowels (A, E, I, O, U) and 21 are consonants (B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z). The candidates must remember this point.

3) The main point of solving the letter coding question is to determine the patterns or rules followed by the given words in the question. To determine the pattern, the candidate must write down the positional values of the word and its code then they will able to identify easily that which operation is used in the question whether it will be addition, subtraction, division, multiples etc.

4) There are some coding rules and patterns to find out the required solution. These rules include:
a) Alphabetical Order of the letters.
b) Reverse alphabetical order of the letters.
c) Numerical Orders or by using mathematical operations such as addition, subtraction, division, multiples etc.
d) Vowels and Consonants in the words or codes.
The candidate has to identify the rule followed by the given word and code in the question to solve the code of the required word. These common rules help the candidates to solve the letter coding reasoning quickly.

3) 65

4) 57

Hint: Determine the sum of the positional value of the letters and add a specific number to it.

Solution

Add 8 to the sum of the positional value of the letters of DENT, to obtain the required code –

(D(4) + E(5) + N(14) + T(20)) + 8 = 43 + 8 = 51

Thus, DENT is coded as 51.

And, LOAD is coded as 40 –

(L(12) + O(15) + A(1) + D(4)) + 8 = 32 + 8 = 40

Thus, LOAD is coded as 40.

Similarly, follow the same pattern for COST –

(C(3) + O(15) + S(19) + T(20)) + 8 = 57 + 8 = 65

Thus, COST is coded as 65. Hence, the third option is correct.

3) Directions: In a certain code language, MADRAS is written as 112 and JAMMU is written as 82. How will PUNJAB be written in that language?

1) 109

2) 104

3) 112

4) 115

Hint: Determine the code by adding the reverse position values of the letters of the given word and then add the total number of letters in the resultant number.

Solution

Add the reverse position values of the letters of the word MADRAS then add the total number of letters in the word to obtain the required code –

M→14; A→26; D→23; R→9; A→26; S→8

Now, add the reverse position values of the word MADRAS then add the total number of letters in the word –

14 + 26 + 23 + 9 + 26 + 8 = 106 + 6 = 112

Thus, MADRAS is coded as 112.

And, JAMMU is written as 82 –

J→17; A→26; M→14; M→14; U→6

Now, add the reverse position values of the word JAMMU then add the total number of letters in the word –

17 + 26 + 14 + 14 + 6 = 77 + 5 = 82

Thus, JAMMU is coded as 82.

Similarly, follow the same pattern for PUNJAB –

P→11; U→6; N→13; J→17; A→26; B→25

Now, add the reverse position values of the word PUNJAB then add the total number of letters in the word –

11 + 6 + 13 + 17 + 26 + 25 = 98 + 6 = 104

So, PUNJAB is coded as 104. Hence, the second option is correct.

4) Directions: In a certain code language, POLISH is written as 89 and CLIP is written as 72. How will CONTROL be written in that language?

1) 89

2) 92

3) 106

4) 99

Hint: Add the opposite position values of the letters of the given words to the total number of letters present in that word.

Solution

The logic here is – The sum of the opposite position values + the total number of letters

POLISH ⇒ P→K = 11; O→L = 12; L→O = 15; I→R = 18; S→H = 8; H→S = 19

The sum of the opposite position values = 11 + 12 + 15 + 18 + 8 + 19 = 83

Total number of letters = 6

The code is 83 + 6 = 89

CLIP ⇒ C→X = 24; L→O = 15; I→R = 18; P→K = 11

The sum of the opposite position values = 24 + 15 + 18 + 11 = 68

Total number of letters = 4

The code is 68 + 4 = 72

Similarly,

CONTROL ⇒ C→X = 24; O→L = 12; N→M = 13; T→G = 7; R→I = 9; O→L = 12; L→O = 15

The sum of the opposite position value = 24 + 12 + 13 + 7 + 9 + 12 + 15 = 92

Total number of letters = 7

The code is 92 + 7 = 99

So, CONTROL is coded as 99. Hence, the fourth option is correct.

5) Directions: In a code language, SPACE is written as 5 – 91 and ROTTEN is written as 6 – 70. How will MEAN be written in that language?

1) 4 – 75

2) 4 – 74

3) 4 – 73

4) 4 – 76

Solution

The first number is equal to the total number of letters and the second number is equal to the sum of the opposite position value of the letters of SPACE, to obtain the required code –

Total number of letters in SPACE = 5

Opposite position value of the letters of SPACE→S = 8(H); P = 11(K); A = 26(Z); C = 24(X); E = 22(V)

The sum of the opposite position values→8 + 11 + 26 + 24 + 22 = 91

Thus, SPACE is coded as 5 – 91.

And, ROTTEN is written as 6 – 70→

Total number of letters in ROTTEN = 6

Opposite position value of the letters ROTTEN→R = 9(I); O = 12(L); T = 7(G); T = 7(G); E = 22(V); N = 13(M)

The sum of the opposite position values→9 + 12 + 7 + 7 + 22 + 13 = 70

Thus, ROTTEN is coded as 6 – 70.

Similarly, follow the same pattern for MEAN→

Total number of letters in MEAN = 4

Opposite position value of the letters MEAN→M = 14(N); E = 22(V); A = 26(Z); N = 13(M)

The sum of the opposite position values→14 + 22 + 26 + 13 = 75

So, MEAN is coded as 4 – 75. Hence, the first option is correct.

Third option: 96, 00, 23, 99 – C, A, and S cannot be represented as 96, 00, and 99 respectively.

Fourth option: 95, 01, 13, 77 – R and S cannot be represented as 13 and 77 respectively.

So, only the second option consists of the numbers through which CARS can be represented. Hence, the second option is correct.

Practice Questions for Chinese Coding

1) Directions: In a certain code language, 629 is coded as namo te fek, 943 is coded as dump to te, and 748 is coded as to fir tako. What is the code for the letter 3 in that language

1) dump

2) to

3) fir

4) te

Hint: Determine the code by comparing the given numbers and words.

Solution

By comparing all the above-coded numbers, we find that –

In sentences 1 and 2, 9 and te are common.

In sentences 2 and 3, 4 and to are common.

The remaining number and the code in sentence 1 are 6/2 and namo/fek; in sentence 2 are 3 and dump; in sentence 3 are 7/8 and fir/tako.

Finally, 9 ⇒ te; 4 ⇒ to; 6/2 ⇒ namo/fek; 3 ⇒ dump

So, 3 will be coded as dump. Hence, the first option is correct.

2) Directions: In a code language, food is fresh is coded as dy in pq, bring fresh food is coded as tq pq dy, and food is hot is coded as dy in to. What is the code for the word fresh?

1) In

2) to

3) pq

4) dy

Hint: Determine the code by comparing the given sentences.

Solution

By comparing all the coded sentences, we find that –

In sentences 1 and 2, food and fresh are common words and pq and dy are common codes.

In sentences 1 and 3, food and is are common words and dy and in are common codes.

The remaining words and code are in sentence 2; bring and tq and in sentence 3; hot and to.

Finally, food ⇒ dy; fresh ⇒ pq; is ⇒ in; bring ⇒ tq; hot ⇒ to

So, fresh will be coded as pq. Hence, the third option is correct.

3) Directions: In a code language, you can start is written as sent room dark, can you read is written as room sent less, and you are good is written as tyre room spin. What is the code for the word can in this language?

1) room

2) sent

3) spin

4) dark

Hint: Compare the statements and determine the common words and code.

Solution

By comparing all the above-coded sentences, we find that –

In sentences 1 and 2, can is the common word and sent is the common code.

In sentences 1, 2 and 3, the common word is you and the common code is room.

The remaining words and codes in sentence 1 are start and dark; in sentence 2 read and less; in sentence 3 are/good and tyre/spin.

Finally, can ⇒ sent; you ⇒ room; start ⇒ room; read ⇒ less; are/good ⇒ tyre/spin

So, can will be coded as sent. Hence, the second option is correct.

4) Directions: In a code language, sign up for sports is written as kri rit vin gab, the sign post fell is written as pri dan rit nei, and the post is closed is written as dan sha fal pri. What is the code for the word fell in this language?

1) pri

2) nei

3) fal

4) rit

Hint: Compare the statements and determine the common words and code.

Solution

By comparing all the above-coded sentences, we find that –

In sentences 1 and 2, the common word is sign and the common code is rit are common.

In sentences 2 and 3, common words are the and post and common codes are pri and dan.

The remaining words and the code in sentence 1 up/for/sports and kri/vin/gab; in sentence 2 fell and nei; in sentence 3 is/closed and sha/fal.

Finally, sign ⇒ rit; the/post ⇒ pri/dan; up/for/sports ⇒ kri/vin/gab; fell ⇒ nei; is/closed ⇒ sha/fal

So, fell will be coded as nei. Hence, the second option is correct.

5) Directions: In a code language, you are tall is coded as la da ma, you workout daily is coded as la pa ka, and daily workout makes you tall is coded as ka pa ja la ma. What is the code for the word makes?

1) ma

2) ja

3) la

4) pa

Hint: Solve the question by comparing the given sentences together.

Solution

By comparing all the three coded sentences, we find that –

In sentences 1, 2, and 3, you and la are common.

In sentences 2 and 3, workout, daily and pa, ka are common.

In sentences 1 and 3, tall and ma are common.

The remaining words and code are in sentence 1; are and da; In sentence 3; makes and ja.

Finally, you ⇒ la; workout ⇒ pa/ka; daily ⇒ pa/ka; tall ⇒ ma; are ⇒ da; makes ⇒ ja.

So, makes is coded as ja. Hence, the second option is correct.

Frequently Asked Questions (FAQs)

1. What is letter coding?

Letter coding reasoning is defined as the coding of the letters by the letters themselves, numbers, symbols etc by following some specific rules or patterns. The topic letter coding reasoning is based on encoding a letter, a number, or a word. Coding letters, numbers, or words is based on various rules and patterns. The candidates have to decode the correct pattern for the coded letters, numbers or words to solve the questions.

2. What are the types of letter coding?

There are five types of letter coding which are as follows:
1) Direct Letter Coding/Letter to Letter Coding
2) Letter to Number Coding
3) Letter to Symbol, Number Coding
4) Chinese Coding
5) Matrix Coding

3. How to solve letter coding?

To solve letter coding questions the candidates must learn the positional values of the alphabet and have basic knowledge of simple arithmetic operations such as addition, subtraction, multiplication, division, multiples etc. The steps for solving the questions of letter coding are given in the above article in detail.

4. What is a letter code example?

The example of letter code is given below:
In a certain code language, COURT is written as ERWUV and DANCE is written as FDPFG. How will EARTH be written in that language?
Solution:
Add 2 and 3 alternately to the place value of the letters of COURT to obtain the required code –
C + 2 = E; O + 3 = R; U + 2 = W; R + 3 = U; T + 2 = V
Thus, COURT is coded as ERWUV.
And, DANCE is written as FDPFG.
D + 2 = F; A + 3 = D; N + 2 = P; C + 3 = F; E + 2 = G
Similarly, follow the same pattern for EARTH –
E + 2 = G; A + 3 = D; R + 2 = T; T + 3 = W; H + 2 = J
So, EARTH is coded as GDTWJ.
