What is the average of the following numbers ?
42 75 89 63 59 72 48

Options

A. 56
B. 58
C. 66
D. 64

Answer

To find the average of the numbers 42, 75, 89, 63, 59, 72, and 48, we will follow these steps:

### Step 1: List the numbers
The numbers we need to find the average of are:
- 42
- 75
- 89
- 63
- 59
- 72
- 48

### Step 2: Calculate the sum of the numbers
Now, we will add all these numbers together:
\[ 42 + 75 + 89 + 63 + 59 + 72 + 48 \]

Calculating step by step:
- \(42 + 75 = 117\)
- \(117 + 89 = 206\)
- \(206 + 63 = 269\)
- \(269 + 59 = 328\)
- \(328 + 72 = 400\)
- \(400 + 48 = 448\)

So, the total sum is \(448\).

### Step 3: Count the total numbers
Next, we need to count how many numbers there are. In this case, we have:
- 1, 2, 3, 4, 5, 6, 7 (total of 7 numbers)

### Step 4: Divide the sum by the total count
Now, we will divide the sum by the total number of values to find the average:
\[ \text{Average} = \frac{\text{Sum}}{\text{Total Numbers}} = \frac{448}{7} \]

Calculating the division:
\[ 448 \div 7 = 64 \]

### Conclusion
The average of the given numbers is \(64\).
