Understanding the Code Language Pattern

The question asks us to decipher a coding pattern used for the word 'CALM' and apply it to the word 'COOK' to find its coded form. This type of problem falls under coding-decoding in logical reasoning, where letters are shifted or rearranged according to a specific rule.

Analyzing the CALM to DCOQ Code

Let's look at the relationship between the letters in 'CALM' and 'DCOQ'. We can compare the positions of each letter in the English alphabet:

From the table, we can clearly see a pattern: the first letter is shifted by +1 position, the second by +2, the third by +3, and the fourth by +4.

Applying the Pattern to COOK

Now, we will apply this same pattern (+1, +2, +3, +4) to the letters of the word 'COOK'.

• First letter 'C': Shift by +1. C (3rd) + 1 = D (4th).
• Second letter 'O': Shift by +2. O (15th) + 2 = Q (17th).
• Third letter 'O': Shift by +3. O (15th) + 3 = R (18th).
• Fourth letter 'K': Shift by +4. K (11th) + 4 = O (15th).

Combining the resulting letters (D, Q, R, O), we get the coded word 'DQRO'.

Matching the Coded Word with Options

We found that 'COOK' is coded as 'DQRO' based on the established pattern from 'CALM' and 'DCOQ'. Let's check the given options:

1. DORQ
2. DPRQ
3. DROQ
4. DQRO

The coded word 'DQRO' matches option 4.

Conclusion: The Code for COOK

Following the logical pattern where each successive letter in the word is shifted by an increasing number of positions in the alphabet (+1, +2, +3, +4), the word 'COOK' is coded as 'DQRO'.

Additional Information: Types of Coding Patterns

Coding-decoding problems often involve different types of patterns. Understanding these can help solve similar questions:

• Letter Shifting: Letters are shifted forward or backward by a fixed number or a varying number, as seen in this problem.
• Direct Letter Coding: Each letter in the original word is directly assigned a specific letter or symbol in the code.
• Position Based Coding: The positions of letters within the word are rearranged.
• Mixed Coding: A combination of the above patterns or involvement of numbers/symbols along with letters.

Always look for a consistent rule or pattern that transforms the given word into its coded form. Applying this identified rule to the new word will give the answer.
