Decoding the Code Language for 'Sharks'

The problem asks us to find the specific code symbol for the word 'Sharks' based on a given coding pattern.

We are given the following coded sentences:

• 'Sharks are fish' is coded as '@ # mt'
• 'Fish eat food' is coded as 'lu mt ak'
• 'Sharks eat fish' is coded as 'mt ak @'

Step-by-Step Code Analysis

1. Compare Sentence 1 and Sentence 3:
   • Sentence 1: 'Sharks are fish' = '@ # mt'
   • Sentence 3: 'Sharks eat fish' = 'mt ak @'
   • Common words: 'Sharks', 'fish'
   • Common codes: '@', 'mt'
   • Conclusion: {'Sharks', 'fish'} correspond to {'@', 'mt'} in some order.
2. Compare Sentence 2 and Sentence 3:
   • Sentence 2: 'Fish eat food' = 'lu mt ak'
   • Sentence 3: 'Sharks eat fish' = 'mt ak @'
   • Common words: 'Fish', 'eat'
   • Common codes: 'mt', 'ak'
   • Conclusion: {'Fish', 'eat'} correspond to {'mt', 'ak'} in some order.
3. Identify the code for 'fish':
   • From step 1, {'Sharks', 'fish'} <-> {'@', 'mt'}
   • From step 2, {'Fish', 'eat'} <-> {'mt', 'ak'}
   • The word 'fish' is common to both comparisons.
   • The code 'mt' is common to both comparisons.
   • Therefore, the code for 'fish' must be 'mt'.
4. Determine the code for 'Sharks':
   • Revisiting step 1: {'Sharks', 'fish'} <-> {'@', 'mt'}
   • Since we established 'fish' = 'mt', the remaining word 'Sharks' must correspond to the remaining code '@'.
   • Therefore, the code for 'Sharks' is '@'.

The code for 'Sharks' in this language is '@'.
