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. 147
B. 579
C. 135
D. 257

Answer

To solve the problem of identifying the number that is different from the others based on divisibility by 3, we will follow these steps:

### Step 1: List the Numbers
The numbers given are:
1. 147
2. 579
3. 135
4. 257

### Step 2: Check Divisibility by 3
We will check each number to see if it is divisible by 3.

- **For 147**:
- Calculation: \( 147 \div 3 = 49 \)
- Result: 147 is divisible by 3.

- **For 579**:
- Calculation: \( 579 \div 3 = 193 \)
- Result: 579 is divisible by 3.

- **For 135**:
- Calculation: \( 135 \div 3 = 45 \)
- Result: 135 is divisible by 3.

- **For 257**:
- Calculation: \( 257 \div 3 \) does not yield a whole number (approximately 85.67).
- Result: 257 is not divisible by 3.

### Step 3: Identify the Odd One Out
From our calculations, we see that:
- 147, 579, and 135 are all divisible by 3.
- 257 is not divisible by 3.

### Conclusion
The number that is different from the others is **257**.
