B. 542
C. 538
D. 526

Answer

To find the average of the numbers 410, 475, 525, 560, and 720, we follow these steps:

### Step 1: Sum the Numbers
First, we need to add all the numbers together.

\[ 410 + 475 + 525 + 560 + 720 \]

### Step 2: Perform the Addition
Let's add them step by step:

- First, add 410 and 475:
\[ 410 + 475 = 885 \]

- Next, add 525 to the result:
\[ 885 + 525 = 1410 \]

- Now, add 560:
\[ 1410 + 560 = 1970 \]

- Finally, add 720:
\[ 1970 + 720 = 2690 \]

So, the total sum of the numbers is:
\[ \text{Sum} = 2690 \]

### Step 3: Count the Numbers
We have a total of 5 numbers.

### Step 4: Calculate the Average
To find the average, we divide the total sum by the count of the numbers:

\[ \text{Average} = \frac{\text{Sum}}{\text{Count}} = \frac{2690}{5} \]

### Step 5: Perform the Division
Now, we divide 2690 by 5:

- 5 goes into 26 five times (5 x 5 = 25), leaving a remainder of 1.
- Bring down the next digit (9), making it 19. 5 goes into 19 three times (5 x 3 = 15), leaving a remainder of 4.
- Bring down the next digit (0), making it 40. 5 goes into 40 eight times (5 x 8 = 40), leaving no remainder.

So, the average is:
\[ \text{Average} = 538 \]

### Final Answer
The average of 410, 475, 525, 560, and 720 is **538**.
