Step 1: Understanding the Concept:
This is a substitution coding problem where each letter in the given words is assigned a specific numerical digit. To find the code for a new word, we must identify the digits assigned to each of its letters from the provided examples.
Step 2: Key Formula or Approach:
Map each letter to its corresponding digit based on its position in the words 'PLAYER' and 'DARE'.
Step 3: Detailed Explanation:
From 'PLAYER' (543976):
\[ P = 5, \quad L = 4, \quad A = 3, \quad Y = 9, \quad E = 7, \quad R = 6 \]
From 'DARE' (8367):
\[ D = 8, \quad A = 3, \quad R = 6, \quad E = 7 \]
(Note that the codes for A, R, and E match in both words, confirming the substitution rule).
Now, to code 'YELP':
\[ Y = 9 \]
\[ E = 7 \]
\[ L = 4 \]
\[ P = 5 \]
Combining these, the code for 'YELP' is 9745.
Step 4: Final Answer:
The code for 'YELP' is 9745.
