  1. 5
  2. 4
  3. 3
  4. 2

Correct answer and explanation

Correct answer: 2

Explanation: āœ… Correct Answer: D) 2 šŸ“š Explanation: Comparing the first and second codes, the common word is 'old' and the common digit is '5'. Thus, 5 = old. Comparing the first and third codes, the common word is 'books' and the common digit is '3'. Thus, 3 = books. In the first code '253' (books are old), since 5 is 'old' and 3 is 'books', the remaining digit '2' must logically stand for 'are'.
