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

Options

A. 37
B. 49
C. 132
D. 154

Answer

To solve the question, we need to identify the number that is different from the others based on a specific characteristic. Let's go through the steps:

### Step-by-Step Solution:

1. **List the Given Numbers**: The numbers provided are 37, 49, 132, and 154.

2. **Identify Characteristics**: We need to determine a common characteristic among the numbers. The numbers can be categorized based on whether they are prime or composite.

3. **Check Each Number**:
- **37**: Check if it is prime. A prime number has only two factors: 1 and itself. Since 37 can only be divided by 1 and 37, it is a prime number.
- **49**: Check if it is prime. The factors of 49 are 1, 7, and 49 (since 49 = 7 x 7). Therefore, 49 is not a prime number; it is a composite number.
- **132**: Check if it is prime. The factors of 132 include 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, and 132. Thus, 132 is also a composite number.
- **154**: Check if it is prime. The factors of 154 include 1, 2, 7, 11, 14, 77, and 154. Therefore, 154 is a composite number.

4. **Compare the Results**:
- 37 is a prime number.
- 49, 132, and 154 are composite numbers.

5. **Identify the Odd One Out**: Since 37 is the only prime number among the given numbers, it is different from the others.

### Conclusion:
The number that is different from the others is **37** because it is the only prime number in the group.
