Code Language Analysis

The question presents a coding puzzle where letters are replaced by digits. We need to find the specific code for the letter 'K' based on the examples provided.

Step 1: Decode the Given Examples

We have the following mappings:

• Word: POKE, Code: 8469
• Word: KIND, Code: 2387

Step 2: Identify Common Elements

To solve this, we compare the letters in the words and the digits in their codes to find commonalities.

• Common Letter: The letter 'K' is present in both 'POKE' and 'KIND'.
• Common Digit: The digit '8' is present in both codes '8469' and '2387'.

Step 3: Establish the Code for 'K'

In substitution ciphers like this, a common letter usually corresponds to a common digit. Since 'K' is the only common letter and '8' is the only common digit, it implies that 'K' is represented by the digit '8'.

Therefore, the code for 'K' is 8.
