The following table embodies the details about the enrollment of students in five different activities namely Swimming, Singing, Drawing, Dancing and Handicraft in a School during the session 2020-21. A total number of 3000 students including 1750 girls have been enrolled in various activities in the school. Based on the data in the table, answer the questions: Activity-wise Enrollment of StudentsActivity Percentage (%) of students enrolled (Out of 3000) Percentage (%) of Girls enrolled (Out of 1750) Swimming 16% 14% Singing 21% 28% Drawing 14% 16 % Dancing 24% 20% Handicraft 25% 22%
What is the total number of girls enrolled in Swimming and Drawing taken together?
Understanding Student Enrollment Data
The problem provides data about student enrollment in different activities in a school. We are given the total number of students, the total number of girls, and the percentage distribution of total students and total girls across five activities.
The table shows the following data:
| Activity | Percentage (%) of students enrolled (Out of 3000) | Percentage (%) of Girls enrolled (Out of 1750) |
|---|---|---|
| Swimming | 16% | 14% |
| Singing | 21% | 28% |
| Drawing | 14% | 16 % |
| Dancing | 24% | 20% |
| Handicraft | 25% | 22% |
We are asked to find the total number of girls enrolled in Swimming and Drawing taken together. The total number of girls enrolled in all activities is 1750.
Calculating Number of Girls in Each Activity
To find the number of girls in a specific activity, we need to multiply the total number of girls by the percentage of girls enrolled in that activity.
Girls enrolled in Swimming:
According to the table, 14% of the total girls are enrolled in Swimming.
Total girls = 1750
Percentage of girls in Swimming = 14%
Number of girls in Swimming = 14% of 1750
Calculation:
\( \text{Number of girls in Swimming} = \frac{14}{100} \times 1750 \)
\( = 0.14 \times 1750 \)
\( = 245 \)
So, 245 girls are enrolled in Swimming.
Girls enrolled in Drawing:
According to the table, 16% of the total girls are enrolled in Drawing.
Total girls = 1750
Percentage of girls in Drawing = 16%
Number of girls in Drawing = 16% of 1750
Calculation:
\( \text{Number of girls in Drawing} = \frac{16}{100} \times 1750 \)
\( = 0.16 \times 1750 \)
\( = 280 \)
So, 280 girls are enrolled in Drawing.
Total Number of Girls in Swimming and Drawing
To find the total number of girls enrolled in Swimming and Drawing together, we add the number of girls in each activity.
Total girls in Swimming and Drawing = (Number of girls in Swimming) + (Number of girls in Drawing)
Total girls in Swimming and Drawing = 245 + 280
\( = 525 \)
Conclusion
The total number of girls enrolled in Swimming and Drawing taken together is 525.
Revision Table: Key Calculations
| Activity | Percentage of Girls Enrolled | Total Girls | Calculated Number of Girls |
|---|---|---|---|
| Swimming | 14% | 1750 | \( \frac{14}{100} \times 1750 = 245 \) |
| Drawing | 16% | 1750 | \( \frac{16}{100} \times 1750 = 280 \) |
| Swimming + Drawing | - | - | \( 245 + 280 = 525 \) |
Additional Information: Data Interpretation Basics
Data interpretation often involves reading tables, charts, and graphs to extract relevant information and perform calculations. Key concepts include:
- Percentages: Understanding how to calculate a percentage of a given number is crucial. The formula is \( \text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100 \) or \( \text{Part} = \frac{\text{Percentage}}{100} \times \text{Whole} \).
- Reading Tables: Carefully reading the rows and columns to identify the correct data points required for the question. Pay attention to what the percentages are based on (e.g., percentage of total students vs. percentage of total girls).
- Combining Data: Questions often require combining data from multiple categories or performing multiple steps. In this case, we calculated girls in two separate activities and then added them.
This type of problem is common in data interpretation sections of various exams, testing your ability to quickly and accurately extract and process information from tables.
