Choose the one which is different from the others.

Options

A. 363
B. 111
C. 243
D. 383

Answer

To solve the problem of identifying the odd one out among the given options, we will analyze each number based on their divisibility by 3.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Option 1: 363
- Option 2: 111
- Option 3: 243
- Option 4: 383

2. **Check Divisibility by 3**: We will check each number to see if it is divisible by 3. A number is divisible by 3 if the sum of its digits is divisible by 3.

3. **Calculate for Option 1 (363)**:
- Sum of digits: 3 + 6 + 3 = 12
- Since 12 is divisible by 3, **363 is divisible by 3**.

4. **Calculate for Option 2 (111)**:
- Sum of digits: 1 + 1 + 1 = 3
- Since 3 is divisible by 3, **111 is divisible by 3**.

5. **Calculate for Option 3 (243)**:
- Sum of digits: 2 + 4 + 3 = 9
- Since 9 is divisible by 3, **243 is divisible by 3**.

6. **Calculate for Option 4 (383)**:
- Sum of digits: 3 + 8 + 3 = 14
- Since 14 is not divisible by 3, **383 is not divisible by 3**.

7. **Conclusion**: After analyzing all options, we find that:
- Options 1 (363), 2 (111), and 3 (243) are all divisible by 3.
- Option 4 (383) is not divisible by 3.

Thus, the odd one out is **Option 4: 383**.
