A lives at the highest even.
Who lives at 16 Oak Ln?
Show answer & explanation
Correct answer: B
Explanation
Based on the given clues, let us determine each person's house number (10, 12, 14, 16, 18, 20):
• C lives at the lowest even-numbered house: C = 10
• A lives at the highest even-numbered house: A = 20
• B's house number is 4 more than F's:
• F lives immediately above D:
Combining these conditions, we have .
From the remaining available numbers {12, 14, 16, 18}:
• If , then and (Valid).
• (If , then , which is already occupied by A).
The only remaining number is 16, which must belong to E.
Final arrangement:
• 10: C
• 12: D
• 14: F
• 16: E
• 18: B
• 20: A
Therefore, E lives at 16 Oak Ln.
