Understanding the Code Language Pattern

The question asks us to decipher a specific code language based on two examples and then apply the same rule to decode a third word. The given examples are:

• 'JAIPUR' is written as 'AJPIRU'
• 'BHOPAL' is written as 'HBPOLA'

We need to find out how 'INDORE' will be written in this code language.

Analyzing the Encoding Rule

Let's examine the first example: 'JAIPUR' transforming into 'AJPIRU'. We can compare the positions of the letters in the original word and the coded word.

Original Word: J A I P U R

Coded Word: A J P I R U

Let's look at the letter pairs:

• The first two letters 'JA' in the original word become 'AJ' in the coded word. The letters are swapped.
• The next two letters 'IP' in the original word become 'PI' (Wait, the coded word is AJPIRU. Let's check the mapping again based on position).

Let's map the letters by their original position to their new position:

This positional mapping above is incorrect as it lists the coded letters in their final order, not showing where the original letters moved. Let's analyze the transformation by looking at which letter from the original word appears at each position in the coded word.

Original Word: J₁ A₂ I₃ P₄ U₅ R₆

Coded Word: A₂ J₁ P₄ I₃ R₆ U₅

Here, the subscript indicates the original position of the letter.

• The letter at original position 2 (A) moves to coded position 1.
• The letter at original position 1 (J) moves to coded position 2.
• The letter at original position 4 (P) moves to coded position 3.
• The letter at original position 3 (I) moves to coded position 4.
• The letter at original position 6 (R) moves to coded position 5.
• The letter at original position 5 (U) moves to coded position 6.

This clearly shows that the letters are swapped in pairs of two adjacent letters:

• (Position 1, Position 2) are swapped.
• (Position 3, Position 4) are swapped.
• (Position 5, Position 6) are swapped.

Let's verify this rule with the second example: 'BHOPAL' transforming into 'HBPOLA'.

Original Word: B H O P A L

Apply the swap rule:

• Swap 1st and 2nd: BH becomes HB
• Swap 3rd and 4th: OP becomes PO
• Swap 5th and 6th: AL becomes LA

Combining these swapped pairs: HB + PO + LA = HBPOLA. This matches the second example, confirming our rule.

Applying the Rule to INDORE

Now we apply the same rule to the word 'INDORE'. The word 'INDORE' has 6 letters.

Original Word: I N D O R E

Positions: 1 2 3 4 5 6

Apply the swap rule to adjacent pairs:

• Swap letters at Position 1 and 2: I N becomes N I
• Swap letters at Position 3 and 4: D O becomes O D
• Swap letters at Position 5 and 6: R E becomes E R

Combine the results of the swaps:

N I + O D + E R = NIODER

So, 'INDORE' will be written as 'NIODER' in this code language.

Checking the Options

Let's compare our result 'NIODER' with the given options:

1. NIODER
2. DINRUP
3. NDOIER
4. DNEERO

Our calculated coded word 'NIODER' matches option 1.

Conclusion

The code language uses a simple pattern of swapping adjacent pairs of letters in the original word. By applying this pattern to 'INDORE', we found the coded word to be 'NIODER'.

Additional Information: Letter Coding and Reasoning

Letter coding is a common type of reasoning question where words are coded based on a specific rule or pattern. To solve such questions, you need to:

• Carefully observe the given examples.
• Identify the pattern or rule used for coding (e.g., shifting letters, reversing order, swapping positions, using opposite letters, or a combination).
• Apply the identified rule to the new word to find its code.

Common patterns include:

• Positional Change: Letters change their positions within the word (like the example solved here - adjacent swap).
• Letter Shifting: Each letter is replaced by a letter a fixed number of positions away in the alphabet (e.g., A becomes C, B becomes D, etc.).
• Reverse Order: The entire word is reversed.
• Opposite Letters: Each letter is replaced by its opposite letter in the alphabet (A is opposite Z, B is Y, etc.).
• Mixed Patterns: A combination of the above rules.

Practicing different types of coding-decoding questions helps in quickly identifying the underlying logic during exams.
