Decoding the Pattern in FORENSIC and DORM

This coding question requires us to identify the specific pattern used to convert letters into numbers for the words 'FORENSIC' and 'DORM'. Once the pattern is understood, we can apply it to find the code for 'CARAMEL'.

Let's examine the given examples:

• 'FORENSIC' is coded as '61218221419183'.
• 'DORM' is coded as '4121813'.

We can compare the letters with their standard alphabetical positions (A=1, B=2, ..., Z=26) and the given codes.

Observing the tables, we notice that some letters (F, R, N, S, C, D, M) are coded using their direct alphabetical position. However, other letters (O, E, I) are coded differently.

Let's check if the letters coded differently are vowels (A, E, I, O, U) and the ones coded directly are consonants. Vowels in FORENSIC are O, E, I. Consonants are F, R, N, S, C. Vowels in DORM are O. Consonants are D, R, M.

This seems to be the distinction. Now let's figure out the coding for vowels.

• O (position 15) is coded as 12. Notice $12 = 27 - 15$.
• E (position 5) is coded as 22. Notice $22 = 27 - 5$.
• I (position 9) is coded as 18. Notice $18 = 27 - 9$.

The pattern is now clear:

• Consonants are coded by their standard alphabetical position.
• Vowels are coded by their reverse alphabetical position ($27 - \text{alphabetical position}$).

Applying the Pattern to Code CARAMEL

Now we apply this identified coding pattern to the word 'CARAMEL'. We will determine if each letter is a consonant or a vowel and apply the corresponding rule.

Concatenating the individual letter codes for 'CARAMEL', we get:

3 (for C) + 26 (for A) + 18 (for R) + 26 (for A) + 13 (for M) + 22 (for E) + 12 (for L)

Resulting code: 3261826132212.

Conclusion: Coding Decoding for CARAMEL

Based on the pattern derived from the coded words 'FORENSIC' and 'DORM', the word 'CARAMEL' is coded as 3261826132212. This involves using the standard alphabetical position for consonants and the reverse alphabetical position ($27 - \text{position}$) for vowels.

Additional Information: Logical Reasoning and Coding

Coding-decoding questions are common in logical reasoning sections of competitive exams. They test your ability to observe patterns and apply rules. The patterns can be based on:

• Alphabetical positions (forward or reverse).
• Skipping letters.
• Vowel/Consonant differentiation.
• Substitution of letters with other letters or symbols.
• Mathematical operations on letter positions.

Practicing various types of coding-decoding problems helps in quickly identifying the underlying logic during the exam.
