Understanding the Coding Language Pattern

The question asks us to decipher a coding language where the word "MATERIAL" is encoded as "NDYLTMGT". We need to find the pattern or rule used for this transformation and then apply it to the word "PURCHASE".

Analyzing the Encoding of MATERIAL

Let's look at the transformation of each letter in "MATERIAL" to the corresponding letter in "NDYLTMGT". We can observe the positional shift or difference in the alphabetical order.

Observing the shifts, we see a pattern: $+1, +3, +5, +7, +2, +4, +6, +8$. The shifts for the letters in odd positions (1st, 3rd, 5th, 7th) are $+1, +5, +2, +6$. The shifts for the letters in even positions (2nd, 4th, 6th, 8th) are $+3, +7, +4, +8$. It seems the shifts for the first four letters are odd numbers increasing by 2 ($1, 3, 5, 7$), and the shifts for the next four letters are even numbers increasing by 2 ($2, 4, 6, 8$). This is the pattern we will apply.

Applying the Pattern to PURCHASE

Now let's apply the identified shift pattern to the word "PURCHASE". The shifts are +1, +3, +5, +7, +2, +4, +6, +8 for the 1st through 8th letters respectively.

Following these shifts, the word "PURCHASE" is encoded as "QXWJJEYM".

Matching with Options

Comparing our result "QXWJJEYM" with the given options:

• Option 1: QWUGJDWJ
• Option 2: QXWJJEYM
• Option 3: QWUGICVI
• Option 4: QXWJIDXL

Our encoded word "QXWJJEYM" matches Option 2.

Conclusion

The coding language uses a specific incremental shift for each letter based on its position in the word. By analyzing the transformation of "MATERIAL" to "NDYLTMGT", we found the shift pattern +1, +3, +5, +7, +2, +4, +6, +8. Applying this pattern to "PURCHASE" gives us the encoded word "QXWJJEYM".

Coding Language Pattern Revision

Understanding the pattern is key in coding language questions. Here's a quick recap of the pattern identified:

• The shift amount increases for each subsequent letter.
• The shifts are: +1, +3, +5, +7 for the first four letters.
• The shifts then reset and become +2, +4, +6, +8 for the next four letters.
• This specific sequence of shifts (+1, +3, +5, +7, +2, +4, +6, +8) is applied to the letters of the word in order.

Additional Information on Letter Encoding

Coding and decoding questions often involve patterns based on:

• Positional Shift: Shifting letters forward or backward in the alphabet by a fixed number or a varying number based on position, letter value, or other rules.
• Reverse Order: Writing the encoded word in reverse order.
• Substitution: Replacing letters with other letters, symbols, or numbers based on a specific key.
• Block Coding: Dividing the word into blocks and applying rules within blocks.
• Vowel/Consonant Rules: Different rules applied to vowels and consonants.

Analyzing the given example is crucial to identify the specific logic used in that particular coding language problem.
