Reasoning Coding and Decoding Tricks: Coding and Decoding are aiming to test the candidate’s ability to solve the given question, which is according to the situation. There are four types of categories that are falling under both coding and decoding.
The below tools are very important for the solution of each Coding and Decoding problems, the solving information was shared in below for candidates to save a lot of time in the examination. Follow the some easy and known tricks and rules.
What is Coding:
A word or text has converted normal language to certain secure/encrypt language, which is mostly used for the information secure purpose.
Normal Information -> Secured Information
What is Decoding:
The information decrypted from encrypting or revealing the original information from the “Encrypt” language.
Secured Information -> Normal Information
There are four various types of questions that may ask in any examination, the explanation has been given of each category along with examples.
Four Types are…
- Number Coding
- Letter Coding
- Substitution Coding
- Mixed number Coding
The Englisg alphabetic order table is need to solve coding and decoding problems
Alphabetic Order table
| A | B | C | D | E | F | G | H | I | J | K | L | M |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
Reverse Alphabetic Order table
| M | L | K | J | I | H | G | F | E | D | C | B | A |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
Number Coding
Example:
If EXAMDAYS is coded as 12345678 and ONLINE is coded as 123987, How is LINEDAY coded?
- 389467
- 343769
- 3987567
- 234976
Solution
EXAMDAYS = 1234567 and ONLINE = 2398
LINEDAY is Coded as;
by using English alphabetic order table
| A | B | C | D | E | F | G | H | I | J | K | L | M |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
The given data is;
| E | 1 |
| X | 2 |
| A | 3 |
| M | 4 |
| D | 5 |
| A | 6 |
| Y | 7 |
| S | 8 |
Another given data is
| O | 1 |
| N | 2 |
| L | 3 |
| I | 9 |
| N | 8 |
| E | 7 |
Then the final targetted code is
| L | 3 |
| I | 9 |
| N | 8 |
| E | 7 |
| D | 5 |
| A | 6 |
| Y | 7 |
The solution is Answer Option: 3
Letter Coding
Example: In certain language EXAMDAYS is written as DAYMAXES. How will TESTEXAM be written in that code language.?
Solution
In the code language EXAMDAYS = DAYMAXES written
The tagetted Word “TESTEXAM” is written as as per below;
Substitution Coding
Example:
In certain code language “786” means “bring me apple, “958” means “Peel green apple”, and “645” means “bring green fruit”. Which of the following is the code for “me”.?
A. 6
B. 7
C. 8
D. 5
Given input data is;
= 786 = bring me apple
= 958 = peel green apple
= 645 = bring green fruit
8 = apple
5 = green
6 = bring
7 = me
Mixed number Coding
Example:
Directions: In a certain code language
- ‘pit dar na’ means ‘your are good’
- ‘dar tok pa’ means ‘good and bad’
- ‘tim na tok’ means ‘they are bad’
In that language, which word stands for ‘they’?
A. na
B. tok
C. tim
D. pit
- ‘pit dar na’ == ‘your are good’
- ‘dar tok pa’ == ‘good and bad’
- ‘tim na tok’ == ‘they are bad’
After removing common words along codes, then “They” = “tim” will come out.
