In each of the following questions, four numbers are given. Out of these three are alike in some way but rest one is different. Choose the one which is different from the other.

Options

A. 372164
B. 376821
C. 318951
D. 319446

Answer

To solve the problem of identifying the different number among the four given options, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: We have four options to consider:
- Option 1: 3, 7, 2, 1, 6, 4
- Option 2: 3, 7, 6, 8, 2, 1
- Option 3: 3, 1, 8, 9, 5, 1
- Option 4: 3, 1, 9, 4, 4, 6

2. **Calculate the Sum of Digits for Each Option**:
- **Option 1**:
- Sum = 3 + 7 + 2 + 1 + 6 + 4 = 23
- **Option 2**:
- Sum = 3 + 7 + 6 + 8 + 2 + 1 = 27
- **Option 3**:
- Sum = 3 + 1 + 8 + 9 + 5 + 1 = 27
- **Option 4**:
- Sum = 3 + 1 + 9 + 4 + 4 + 6 = 27

3. **Compare the Sums**:
- The sums calculated are:
- Option 1: 23
- Option 2: 27
- Option 3: 27
- Option 4: 27
- Here, we can see that Options 2, 3, and 4 all have a sum of 27, while Option 1 has a sum of 23.

4. **Identify the Different Option**:
- Since Option 1 has a different sum (23) compared to the other three options (27), we can conclude that Option 1 is the one that is different.

### Final Answer:
- The option that is different from the others is **Option 1: 3, 7, 2, 1, 6, 4**.
