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

Options

A. 34-12
B. 43-30
C. 52-21
D. 62-19

Answer

To solve the problem of identifying the odd numeral pair from the given options, we will analyze each pair based on the sum of their digits and the difference between these sums.

### Step-by-Step Solution:

1. **Analyze the first pair: 34 and 12**
- Sum of digits of 34: \(3 + 4 = 7\)
- Sum of digits of 12: \(1 + 2 = 3\)
- Difference: \(7 - 3 = 4\)

2. **Analyze the second pair: 43 and 30**
- Sum of digits of 43: \(4 + 3 = 7\)
- Sum of digits of 30: \(3 + 0 = 3\)
- Difference: \(7 - 3 = 4\)

3. **Analyze the third pair: 52 and 12**
- Sum of digits of 52: \(5 + 2 = 7\)
- Sum of digits of 12: \(1 + 2 = 3\)
- Difference: \(7 - 3 = 4\)

4. **Analyze the fourth pair: 62 and 19**
- Sum of digits of 62: \(6 + 2 = 8\)
- Sum of digits of 19: \(1 + 9 = 10\)
- Difference: \(8 - 10 = -2\) (or \(10 - 8 = 2\))

5. **Comparison of differences:**
- For the pairs (34, 12), (43, 30), and (52, 12), the difference of the sums of their digits is 4.
- For the pair (62, 19), the difference is not 4 (it is 2).

6. **Conclusion:**
- The odd numeral pair is **62 and 19** because it does not follow the same rule as the other pairs.

### Final Answer:
The odd numeral pair is **62 and 19**.
