Options

A. 385
B. 572
C. 671
D. 427

Answer

To solve the question of identifying the odd one out from the given options, we will analyze each option based on the relationship between the digits.

### Step-by-Step Solution:

1. **Identify the Options**: We have four options:
- Option 1: 385
- Option 2: 572
- Option 3: 671
- Option 4: 427

2. **Analyze Each Option**:
- **Option 1: 385**
- The middle digit is 8.
- Check if 8 equals the sum of the other two digits:
- 3 + 5 = 8 (True)

- **Option 2: 572**
- The middle digit is 7.
- Check if 7 equals the sum of the other two digits:
- 5 + 2 = 7 (True)

- **Option 3: 671**
- The middle digit is 7.
- Check if 7 equals the sum of the other two digits:
- 6 + 1 = 7 (True)

- **Option 4: 427**
- The middle digit is 2.
- Check if 2 equals the sum of the other two digits:
- 4 + 7 = 11 (False)

3. **Conclusion**:
- Options 1, 2, and 3 have their middle digit equal to the sum of the other two digits.
- Option 4 does not satisfy this condition because 2 is not equal to 11.

Therefore, the option that is different from the others is **Option 4: 427**.
