Some Basic Things to Remember

Letters positions in forward alphabetical order: Tricks to learn position of alphabet

EJOTY where E=5, J=10, O=15, T=20 & Y=25

CFILORUX where C = 3, F = 6, I = 9, L = 12, O = 15, R = 18, U = 21 & X = 24

DHLPTX where D = 4, H = 8, L = 12, P = 16, T = 20, X = 24

Letters positions in backward or reverse alphabetical order: Opposite of Each Letter Some of the major types of coding logics are

• Constant addition in the position of letters.
• Constant subtraction in the position of letters.
• Denoting the position of letters in the whole alphabetical order.
• Addition of the positions of all the letters to make code for the word.
• Constant addition and subtraction alternatively in the position of all the letters.
• Square of the number of letters in the word.
• Arranging the letters in the alphabetical order.
• Arrangement of letters in the word given in reverse order.
• Interchanging each pair of the letters, in the given word.
• Constant addition and then reversal of the letters to form the final word.

## Coding Decoding Tricks (कोडिंग-डिकोडिंग ट्रिक्स)

 Trick 1

Coding By Letter Shifting

Shortcut Approach

• Observe alphabets given in the code carefully.
• Find the sequence it follows whether it is ascending / descending
• Detect the rule in which the alphabets follow.
• Fill the appropriate letter in the blank given.

Example: If ‘GOOD’ is coded as ‘HPPE’, then how will you code ‘BOLD’?

Solution: CPME

Explanation:

Here, every letter of the word ‘GOOD’ shifts one place in forward alphabetical sequence. Similarly, every letter in the word ‘BOLD’ will move one place in forward alphabetical sequence as given below: Code for ‘BOLD’ will be ‘CPME’.

उदाहरण: किसी सांकेतिक भाषा में ‘NAME’ को ‘MZLD’ लिखा जाता है तो उसी सांकेतिक भाषा में ‘SAME’ को क्या लिखा जाएगा?

समाधान: RZLD

विवरण: इसी तरह, ‘SAME’ को ‘RZLD’ लिखा जाएगा

उदाहरण: किसी सांकेतिक भाषा में ‘FACT’ को ‘IDFW’ लिखा जाता है तो उसी सांकेतिक भाषा में ‘DEEP’ को क्या लिखा जाएगा?

समाधान: GHHS

विवरण: इसी तरह, ‘DEEP’ को ‘GHHS’ लिखा जाएगा

 Trick 2

Coding In Fiction Language

Shortcut Approach

• Firstly, write the words and their codes as given in the question in straight line with an arrow in middle.
• Now, find the common words and their corresponding codes.
• Encircle each pair with the same shape.
• Finally, we have each word and its corresponding code.

Example: In a certain code language ‘over and above’ is written as ‘da pa ta’ and ‘old and beautiful’ is written as ‘Sa na pa’. How is ‘over’ written in that code language?

Solution: either ‘da’ or ‘ta’

Explanation: Clearly, ‘and’ is common in both and a common code is ‘Pa’.

Code for ‘and’ must be ‘Pa’.

Code for ‘over’ = ‘da’ or ‘ta’.

Code for above = ‘da’ or ‘ta’.

Code for old = ‘Sa’ or ‘na’

Code for beautiful = ‘Sa’ or ‘na’

We can’t certainly say what will be exact code for ‘over’. But it is sure that code for ‘over’ must be either ‘da’ or ‘ta’.

Example: In a certain code language,

(a) ‘pod na joc’ means ‘very bright boy’;

(b) ‘tam nu pod’ means ‘the boy comes’;

(c) ‘nu per ton’ means ‘keep the doll’;

(d) ‘joc ton su’ means ‘very good doll’.

Which of the following means ‘bright’ in the same code language?

Solution: na

Explanation:

In statements (a) and (b), the common code word is ‘pod’ and the common word is ‘boy’.

So, ‘pod’ stands for ‘boy’.

In statements (a) and (d), the common code word is ‘joc’ and the common word is ‘very’.

So, ‘joc’ stands for ‘very’.

So, in (a) ‘na’ stands for ‘bright’.
