Find the average of the following set of scores :
539, 741, 326, 461, 654, 952, 128, 543

Options

A. 543
B. 523
C. 608
D. 572

Answer

To find the average of the given set of scores, we will follow these steps:

### Step 1: List the scores
The scores given are:
- 539
- 741
- 326
- 461
- 654
- 952
- 128
- 543

### Step 2: Calculate the sum of the scores
We will add all the scores together:
\[ 539 + 741 + 326 + 461 + 654 + 952 + 128 + 543 \]

Calculating step-by-step:
1. \(539 + 741 = 1280\)
2. \(1280 + 326 = 1606\)
3. \(1606 + 461 = 2067\)
4. \(2067 + 654 = 2721\)
5. \(2721 + 952 = 3673\)
6. \(3673 + 128 = 3801\)
7. \(3801 + 543 = 4344\)

So, the total sum of the scores is \(4344\).

### Step 3: Count the number of scores
Next, we count how many scores there are:
- There are 8 scores in total.

### Step 4: Calculate the average
Now, we will calculate the average by dividing the total sum by the number of scores:
\[ \text{Average} = \frac{\text{Sum of scores}}{\text{Number of scores}} = \frac{4344}{8} \]

Calculating the division:
1. \(4344 \div 8 = 543\)

### Final Answer
The average of the given set of scores is **543**.
