Analyzing University Enrollment Data

The problem asks us to identify the year in which the total number of girls enrolled across three different universities (A, B, and C) is the second highest, based on the provided table. To solve this, we need to calculate the total number of girls enrolled in all three universities for each year from 2015 to 2019.

Calculating Total Enrollment per Year

We sum the number of girls enrolled in Universities A, B, and C for each specific year.

• For the year 2015: $$ \text{Total}_{2015} = 15,000 + 10,000 + 5,000 = 30,000 $$
• For the year 2016: $$ \text{Total}_{2016} = 10,000 + 17,500 + 20,000 = 47,500 $$
• For the year 2017: $$ \text{Total}_{2017} = 22,500 + 12,000 + 15,000 = 49,500 $$
• For the year 2018: $$ \text{Total}_{2018} = 20,000 + 25,000 + 15,000 = 60,000 $$
• For the year 2019: $$ \text{Total}_{2019} = 25,000 + 20,000 + 22,500 = 67,500 $$

Comparing Total Enrollment Across Years

Now we have the total number of girls enrolled in all three universities for each year:

• 2015: 30,000
• 2016: 47,500
• 2017: 49,500
• 2018: 60,000
• 2019: 67,500

Let's list these totals in descending order to find the highest and second highest values.

1. 2019: 67,500 (Highest total)
2. 2018: 60,000 (Second highest total)
3. 2017: 49,500
4. 2016: 47,500
5. 2015: 30,000

The highest total number of girls enrolled is 67,500 in the year 2019. The second highest total number of girls enrolled is 60,000, which occurred in the year 2018.

Conclusion

Based on the calculations, the total number of girls enrolled in all three Universities together is 2nd highest for the year 2018.

Additional Information: Interpreting Data Tables

Data tables are a common way to organize information, making it easier to read and analyze. When working with tables, it's important to:

• Read the title or caption to understand what the table is about.
• Examine the column headers and row labels to know what each entry represents.
• Look for patterns or trends in the data.
• Perform calculations (like sum, average, difference) as required by the question.
• Always double-check calculations to ensure accuracy.

In this problem, summing across universities for each year allowed us to compare the overall enrollment performance of the university system over different years and find the year with the second highest total.
