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

Options

A. `117:13`
B. `162:18`
C. `171:19`
D. `304:16`

Answer

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

### Step-by-Step Solution:

1. **Identify the Pairs:**
- Option 1: (117, 13)
- Option 2: (162, 18)
- Option 3: (171, 19)
- Option 4: (304, 16)

2. **Analyze Option 1 (117, 13):**
- Check if the second number (13) multiplied by 9 equals the first number (117).
- Calculation:
\[ 13 \times 9 = 117 \]
- This relationship holds true.

3. **Analyze Option 2 (162, 18):**
- Check if the second number (18) multiplied by 9 equals the first number (162).
- Calculation:
\[ 18 \times 9 = 162 \]
- This relationship holds true.

4. **Analyze Option 3 (171, 19):**
- Check if the second number (19) multiplied by 9 equals the first number (171).
- Calculation:
\[ 19 \times 9 = 171 \]
- This relationship holds true.

5. **Analyze Option 4 (304, 16):**
- Check if the second number (16) multiplied by 9 equals the first number (304).
- Calculation:
\[ 16 \times 9 = 144 \]
- This relationship does not hold true as 144 is not equal to 304.

6. **Conclusion:**
- The first three options follow the same pattern where the second number multiplied by 9 equals the first number. However, the fourth option does not follow this pattern.
- Therefore, the odd numeral pair is **Option 4: (304, 16)**.
