Finding Average Pages for Printer C

The question asks for the average number of pages printed by printer C over four specific days: Monday, Wednesday, Thursday, and Friday. To find the average, we need to sum the pages printed on these four days and then divide by the number of days (which is 4).

Extracting Data for Printer C

Let's look at the provided table and identify the number of pages printed by printer C on the required days:

• Monday: 35 pages
• Wednesday: 33 pages
• Thursday: 32 pages
• Friday: 37 pages

We can also visualize this specific data extracted from the full table:

Calculating the Total Pages

Now, we sum the number of pages printed by printer C on these four days:

Total Pages $= 35 + 33 + 32 + 37$

Total Pages $= 137$

Calculating the Average Pages

The average is calculated by dividing the total number of pages by the number of days (4).

Average Pages $= \frac{\text{Total Pages}}{\text{Number of Days}}$

Average Pages $= \frac{137}{4}$

Average Pages $= 34.25$

Therefore, the average number of pages printed by printer C on Monday, Wednesday, Thursday, and Friday is 34.25.

Additional Information: Understanding Averages from Data Tables

Calculating the average is a fundamental concept in data analysis. When working with tables showing data over different categories (like printers) and time periods (like days), you often need to find averages for specific subsets of the data, as done in this problem.

• The average (or mean) gives a single value that represents the central tendency of a set of numbers.
• It is calculated as the sum of all values divided by the count of the values.
• In data interpretation questions, carefully read which specific entries from the table are required for the calculation (e.g., specific printer, specific days).
• Data interpretation problems frequently involve calculations like sum, average, ratio, percentage increase/decrease based on the data presented in tables, charts, or graphs. Practicing these types of questions helps improve quantitative aptitude skills.
