Understanding the Coding Language Pattern

This question involves a coding and decoding task where words are transformed into codes based on a specific rule or pattern. We are given two examples of coded words: 'RAJAT' is coded as 'UCMCW', and 'NIRAJ' is coded as 'QKUCM'. Our goal is to identify the underlying pattern and then apply it to code the word 'MUKUL'.

Let's analyze the transformation of each letter in the first example, 'RAJAT' to 'UCMCW'. We can look at the position of each letter in the English alphabet (A=1, B=2, ..., Z=26).

From the analysis of 'RAJAT', the pattern of shifts in letter positions appears to be +3, +2, +3, +2, +3.

Let's verify this pattern with the second example, 'NIRAJ' to 'QKUCM':

The pattern (+3, +2, +3, +2, +3) is confirmed by the second example 'NIRAJ' to 'QKUCM'. The pattern alternates between adding 3 and adding 2 to the letter's alphabetical position.

Applying the Code to 'MUKUL'

Now we apply the identified pattern (+3, +2, +3, +2, +3) to the word 'MUKUL'.

• M: The first letter is M. Its position is 13. Applying the first shift (+3), $13 + 3 = 16$. The 16th letter is P.
• U: The second letter is U. Its position is 21. Applying the second shift (+2), $21 + 2 = 23$. The 23rd letter is W.
• K: The third letter is K. Its position is 11. Applying the third shift (+3), $11 + 3 = 14$. The 14th letter is N.
• U: The fourth letter is U. Its position is 21. Applying the fourth shift (+2), $21 + 2 = 23$. The 23rd letter is W.
• L: The fifth letter is L. Its position is 12. Applying the fifth shift (+3), $12 + 3 = 15$. The 15th letter is O.

Combining the coded letters, 'MUKUL' is coded as 'PWNWO'.

Conclusion

Based on the consistent pattern observed in the given examples, the word 'MUKUL' is coded as 'PWNWO'. We compare this result with the given options to find the correct answer.

• Option 1: PWNWO
• Option 2: OXMXN
• Option 3: PWNXO
• Option 4: OXNWO

The coded word 'PWNWO' matches Option 1.

Additional Information: Types of Coding-Decoding

Coding-decoding questions are common in reasoning sections of competitive exams. They test your ability to identify patterns in how words, letters, or numbers are transformed. Common types include:

• Letter Coding: Letters are shifted by a certain number of positions (like in this question), or replaced by other letters based on a pattern.
• Number Coding: Words are coded into numbers based on letter positions, count of letters, or other rules.
• Symbol Coding: Words or letters are replaced by symbols.
• Mixed Coding: A mix of letter, number, and symbol coding, often presented as sentences coded into other sentences using different words/codes.
• Word Coding: Entire words are coded as other words.

Solving these questions requires careful observation, pattern recognition, and logical deduction.
