Choose the odd numeral pair/group in the following questions.

To identify the odd numeral pair, we need to analyze the relationship between the two numbers in each option.

Analysis of the Patterns
Let's look at the digits of each pair to see if there is a consistent rule:

Option 1: 14_41

Relationship: The second number is the reverse of the digits of the first number.

Option 2: 45_54

Relationship: The second number is the reverse of the digits of the first number.

Option 3: 37_73

Relationship: The second number is the reverse of the digits of the first number.

Option 4: 35_66

Relationship: This pair does not follow the reversal pattern. If it followed the rule, it would be 35_53.

Conclusion
Options 1, 2, and 3 all follow the pattern where the second number is simply the digits of the first number reversed. Option 4 is the odd pair because it does not follow this rule.
