Choose the odd numeral pair in each of the following questions :

Options

A. 18, 108
B. 23, 138
C. 20, 80
D. 26, 156

Answer

To solve the problem of finding the odd numeral pair among the given options, we will analyze each pair to determine if there is a consistent relationship between the two numbers in each pair.

### Step-by-Step Solution:

1. **Analyze Option 1: (18, 108)**
- We check the relationship by multiplying the first number by 6.
- Calculation: \( 18 \times 6 = 108 \)
- This pair follows the pattern.

2. **Analyze Option 2: (23, 138)**
- Again, we multiply the first number by 6.
- Calculation: \( 23 \times 6 = 138 \)
- This pair also follows the pattern.

3. **Analyze Option 3: (20, 80)**
- We multiply the first number by 6.
- Calculation: \( 20 \times 6 = 120 \)
- Here, 120 does not equal 80, so this pair does not follow the pattern.

4. **Analyze Option 4: (26, 156)**
- We multiply the first number by 6.
- Calculation: \( 26 \times 6 = 156 \)
- This pair follows the pattern as well.

5. **Conclusion:**
- From our analysis, Options 1, 2, and 4 all follow the pattern of multiplying the first number by 6 to get the second number.
- Option 3 (20, 80) does not follow this pattern, making it the odd pair out.

### Final Answer:
The odd numeral pair is **Option 3: (20, 80)**.
