Find the sum of `8` numbers with mean `12`.

Options

A. `96`
B. `86`
C. `89`
D. `112`

Answer

To find the sum of 8 numbers with a mean of 12, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the formula for Mean**:
The mean (average) is calculated using the formula:
\[ \text{Mean} = \frac{\text{Sum of all observations}}{\text{Number of observations}} \]

2. **Identify the given values**:
In this problem, we know:
- Mean = 12
- Number of observations = 8

3. **Set up the equation**:
Using the formula for mean, we can express the sum of the observations (let's call it \( S \)):
\[ 12 = \frac{S}{8} \]

4. **Solve for the Sum (S)**:
To find \( S \), we can rearrange the equation:
\[ S = 12 \times 8 \]

5. **Calculate the result**:
Now, we perform the multiplication:
\[ S = 96 \]

6. **Conclusion**:
Therefore, the sum of the 8 numbers is \( 96 \).

### Final Answer:
The sum of the 8 numbers is **96**.
