Solving Letter Coding Problems

This question involves a simple letter coding system where each letter in the original word is replaced by a specific letter according to a given rule. We are provided with the code for four letters: 'E', 'I', 'C', and 'D'. Our task is to apply this same code to the word 'DECIDE' to find its coded form.

Analyzing the Given Code

The question explicitly provides the mapping for certain letters:

• 'E' is coded as 'O'
• 'I' is coded as 'W'
• 'C' is coded as 'F'
• 'D' is coded as 'Y'

We need to use these exact mappings for the letters that appear in the word 'DECIDE'.

Applying the Code to DECIDE

Let's break down the word 'DECIDE' letter by letter and apply the given coding rules:

1. The first letter is 'D'. According to the code, 'D' is written as 'Y'.
2. The second letter is 'E'. According to the code, 'E' is written as 'O'.
3. The third letter is 'C'. According to the code, 'C' is written as 'F'.
4. The fourth letter is 'I'. According to the code, 'I' is written as 'W'.
5. The fifth letter is 'D'. According to the code, 'D' is written as 'Y'.
6. The sixth letter is 'E'. According to the code, 'E' is written as 'O'.

Combining the coded letters in order, we get the coded word for 'DECIDE'.

Step-by-Step Coding of DECIDE

Let's put it in a clear sequence:

• D → Y
• E → O
• C → F
• I → W
• D → Y
• E → O

So, the word 'DECIDE' is coded as Y O F W Y O.

We can also represent this coding in a table format for clarity:

Therefore, the coded form of 'DECIDE' is 'YOFWYO'.

Conclusion

By applying the specified letter coding rules one by one to each letter of 'DECIDE', we determined the correct coded word. This type of problem tests your ability to follow given patterns and apply them consistently.

Additional Information: Understanding Coding and Decoding

Coding and decoding questions are common in logical reasoning sections of various exams. They involve translating information from one form to another based on a specific rule or pattern. In letter coding, the pattern often involves shifting letters by a certain number of positions in the alphabet, replacing letters with other letters, or using a combination of these methods.

• Coding: The process of converting a word, number, or series into a secret code based on a specific rule.
• Decoding: The process of converting the coded message back into its original form by applying the reverse of the coding rule.

To solve such problems, carefully observe the given examples of coding, identify the rule, and then apply that rule to the new word or number provided in the question. Practice with different types of coding patterns helps in quickly identifying the underlying logic.
