In these type of questions, certain pairs of numbers are given out of which all except one are similar in some manner while one is different. The numbers in these similar pairs may have the same property or may be related to each other according to the same rule. The candidate is required to choose the odd pair.

Options

A. 24-21
B. 46-32
C. 62-23
D. 84-24

Answer

To solve the problem of finding the odd pair among the given options, we will analyze each pair of numbers based on the relationship described in the question.

### Step-by-step Solution:

1. **Identify the pairs:**
- Option 1: (24, 21)
- Option 2: (46, 32)
- Option 3: (62, 23)
- Option 4: (84, 24)

2. **Analyze Option 1: (24, 21)**
- Multiply the second number (21) by 2:
\( 21 \times 2 = 42 \)
- Reverse the digits of 42:
- The reverse of 42 is 24.
- Since the first number is 24, this pair follows the rule.

3. **Analyze Option 2: (46, 32)**
- Multiply the second number (32) by 2:
\( 32 \times 2 = 64 \)
- Reverse the digits of 64:
- The reverse of 64 is 46.
- Since the first number is 46, this pair also follows the rule.

4. **Analyze Option 3: (62, 23)**
- Multiply the second number (23) by 2:
\( 23 \times 2 = 46 \)
- Reverse the digits of 46:
- The reverse of 46 is 64.
- The first number is 62, which does not match 64. This pair does not follow the rule.

5. **Analyze Option 4: (84, 24)**
- Multiply the second number (24) by 2:
\( 24 \times 2 = 48 \)
- Reverse the digits of 48:
- The reverse of 48 is 84.
- Since the first number is 84, this pair follows the rule.

6. **Conclusion:**
- Options 1, 2, and 4 follow the same pattern, while Option 3 does not. Therefore, the odd pair is **Option 3: (62, 23)**.

### Final Answer:
The odd pair is **(62, 23)**.
