Explanation
Let's break down the given code relationships:
- "564" → "study very hard"
- "736" → "hard work pays"
- "423" → "study and work"
Now, let's identify the code for "work":
- The word "work" appears in the second and third codes: "736" (hard work pays) and "423" (study and work).
- The common number in both "736" and "423" is "3".
- Therefore, "3" represents "work".
