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

Options

A. 21-24
B. 28-32
C. 54-62
D. 70-80

Answer

To solve the problem of choosing the odd numeral pair from the given options, we will analyze the pairs step by step.

### Given Options:
1. (21, 24)
2. (28, 32)
3. (54, 62)
4. (70, 80)

### Step 1: Analyze the Pairs
We will look for a common ratio or pattern in each pair.

#### Pair 1: (21, 24)
- The difference between 24 and 21 is 3.
- The ratio of 24 to 21 is \( \frac{24}{21} \) which simplifies to \( \frac{8}{7} \).

#### Pair 2: (28, 32)
- The difference between 32 and 28 is 4.
- The ratio of 32 to 28 is \( \frac{32}{28} \) which simplifies to \( \frac{8}{7} \).

#### Pair 3: (54, 62)
- The difference between 62 and 54 is 8.
- The ratio of 62 to 54 is \( \frac{62}{54} \) which simplifies to \( \frac{31}{27} \).

#### Pair 4: (70, 80)
- The difference between 80 and 70 is 10.
- The ratio of 80 to 70 is \( \frac{80}{70} \) which simplifies to \( \frac{8}{7} \).

### Step 2: Compare the Ratios
Now we will compare the ratios obtained from each pair:
- Pair 1: \( \frac{8}{7} \)
- Pair 2: \( \frac{8}{7} \)
- Pair 3: \( \frac{31}{27} \)
- Pair 4: \( \frac{8}{7} \)

### Step 3: Identify the Odd Pair
From the analysis, we can see that:
- Pairs 1, 2, and 4 have the same ratio of \( \frac{8}{7} \).
- Pair 3 has a different ratio of \( \frac{31}{27} \).

Thus, the odd numeral pair is **(54, 62)**.

### Final Answer:
The odd numeral pair is **(54, 62)**.
