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

Options

A. 140-45
B. 110-35
C. 100-30
D. 80-25

Answer

To solve the problem of choosing the odd numeral pair, we will analyze each pair systematically to identify the one that does not follow the same pattern as the others.

### Step-by-Step Solution:

1. **Identify the Pairs**: We have the following pairs:
- Pair 1: (140, 45)
- Pair 2: (110, 35)
- Pair 3: (130, 80)
- Pair 4: (100, 25)

2. **Analyze Pair 1 (140, 45)**:
- Multiply the second number (45) by 3:
\[ 45 \times 3 = 135 \]
- Add 5 to the result:
\[ 135 + 5 = 140 \]
- This confirms that the first pair follows the pattern.

3. **Analyze Pair 2 (110, 35)**:
- Multiply the second number (35) by 3:
\[ 35 \times 3 = 105 \]
- Add 5 to the result:
\[ 105 + 5 = 110 \]
- This confirms that the second pair also follows the pattern.

4. **Analyze Pair 3 (130, 80)**:
- Multiply the second number (80) by 3:
\[ 80 \times 3 = 240 \]
- Add 5 to the result:
\[ 240 + 5 = 245 \]
- This does not equal 130, indicating that this pair does not follow the pattern.

5. **Analyze Pair 4 (100, 25)**:
- Multiply the second number (25) by 3:
\[ 25 \times 3 = 75 \]
- Add 5 to the result:
\[ 75 + 5 = 80 \]
- This confirms that the fourth pair does not follow the pattern as it should yield 100, not 80.

6. **Conclusion**: The odd pair is Pair 3 (130, 80) because it does not follow the same pattern as the others.

### Final Answer:
The odd numeral pair is **(130, 80)**.
