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

Options

A. `12:96`
B. `13:117`
C. `15:120`
D. `16:128`

Answer

To solve the problem of choosing the odd numeral pair from the given options, we will analyze each pair to identify any consistent relationship between the two numbers in each pair.

### Step-by-Step Solution:

1. **Identify the pairs:**
- Option 1: 12 and 96
- Option 2: 13 and 117
- Option 3: 15 and 120
- Option 4: 16 and 128

2. **Examine the relationship in each pair:**
- **Option 1:**
- Check if 12 multiplied by a certain number gives 96.
- \( 12 \times 8 = 96 \)
- So, the relationship is \( 12 \times 8 = 96 \).

- **Option 2:**
- Check if 13 multiplied by a certain number gives 117.
- \( 13 \times 9 = 117 \)
- So, the relationship is \( 13 \times 9 = 117 \).

- **Option 3:**
- Check if 15 multiplied by a certain number gives 120.
- \( 15 \times 8 = 120 \)
- So, the relationship is \( 15 \times 8 = 120 \).

- **Option 4:**
- Check if 16 multiplied by a certain number gives 128.
- \( 16 \times 8 = 128 \)
- So, the relationship is \( 16 \times 8 = 128 \).

3. **Compare the relationships:**
- Options 1, 3, and 4 all have a consistent multiplier of 8.
- Option 2 has a different multiplier of 9.

4. **Identify the odd pair:**
- Since Options 1, 3, and 4 follow the pattern of multiplying by 8, while Option 2 is different (multiplying by 9), we conclude that Option 2 is the odd pair.

### Final Answer:
The odd numeral pair is **Option 2: 13 and 117**.
