Analyzing School Enrollment Data
The question asks us to find the total number of girls enrolled in all three schools (A, B, and C) in the year 2017 and express this total as a percentage of the number of girls enrolled in School C in the year 2020. We need to use the data provided in the table to perform this calculation.
Here is the table showing the year-wise enrollment of girls:
| Year | Enrollment of Girls in Schools | ||
|---|---|---|---|
| A | B | C | |
| 2017 | 200 | 150 | 100 |
| 2018 | 150 | 225 | 250 |
| 2019 | 275 | 150 | 199 |
| 2020 | 250 | 300 | 200 |
| 2021 | 300 | 250 | 275 |
Step-by-Step Calculation
Step 1: Find the total number of girls enrolled in all three schools in the year 2017.
From the table, the enrollments in 2017 are:
- School A: 200
- School B: 150
- School C: 100
Total enrollment in 2017 = Enrollment in School A + Enrollment in School B + Enrollment in School C
Total enrollment in 2017 = $200 + 150 + 100 = 450$
Step 2: Find the number of girls enrolled in School C in the year 2020.
From the table, the enrollment in School C in 2020 is 200.
Step 3: Calculate the total enrollment in 2017 as a percentage of the enrollment in School C in 2020.
The formula to calculate the percentage is:
$$ \text{Percentage} = \left( \frac{\text{Total enrollment in 2017}}{\text{Enrollment in School C in 2020}} \right) \times 100 $$
Substituting the values we found:
$$ \text{Percentage} = \left( \frac{450}{200} \right) \times 100 $$
$$ \text{Percentage} = 2.25 \times 100 $$
$$ \text{Percentage} = 225 $$
Therefore, the total number of girls enrolled in all three Schools in the year 2017 is 225% of the number of girls enrolled in School C in the year 2020.
Revision Table: Key Data Points
| Metric | Value | Year/School |
|---|---|---|
| Enrollment School A | 200 | 2017 |
| Enrollment School B | 150 | 2017 |
| Enrollment School C | 100 | 2017 |
| Total Enrollment | 450 | 2017 (A+B+C) |
| Enrollment School C | 200 | 2020 |
| Calculated Percentage | 225% | (Total 2017 / C 2020) * 100 |
Additional Information on Percentage Calculations
Percentages are a way of expressing a part of a whole as a fraction of 100. The formula for percentage is:
$$ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 $$
In this question, the 'Part' is the total enrollment in 2017, and the 'Whole' (or the base for comparison) is the enrollment in School C in 2020. It's important to correctly identify the 'Part' and the 'Whole' when calculating percentages.
When the 'Part' is greater than the 'Whole', the resulting percentage will be greater than 100%, as seen in this problem. This indicates that the total enrollment in 2017 was more than double the enrollment in School C in 2020.
