What will be the average of the following set of scores ? 78,69,54,94,21,48,77

Options

A. 63
B. 66
C. 67
D. 64

Explanation

To find the average of the given set of scores (78, 69, 54, 94, 21, 48, 77), we will follow these steps:

### Step 1: Identify the numbers
The scores provided are:
- 78
- 69
- 54
- 94
- 21
- 48
- 77

### Step 2: Count the number of terms
We need to find out how many scores there are in total. Here, we have:
- Total number of scores = 7

### Step 3: Calculate the sum of the scores
Now, we will add all the scores together:
- \( 78 + 69 + 54 + 94 + 21 + 48 + 77 \)

Let's break it down:
- \( 78 + 69 = 147 \)
- \( 147 + 54 = 201 \)
- \( 201 + 94 = 295 \)
- \( 295 + 21 = 316 \)
- \( 316 + 48 = 364 \)
- \( 364 + 77 = 441 \)

So, the total sum of the scores is \( 441 \).

### Step 4: Calculate the average
To find the average, we divide the total sum by the number of scores:
- Average = \( \frac{Total \, Sum}{Number \, of \, Terms} = \frac{441}{7} \)

Now, performing the division:
- \( 441 \div 7 = 63 \)

### Final Answer
Thus, the average of the given set of scores is **63**.
