Direction: Consider the following table that shows the number of girls enrolled in three different Universities A, B and C over the years 2015 to 2019. Based on the data in the table, answer the question.Year-wise Number of Girls in Different Universities Year Number of girls in a University A B C 2015 15,000 10,000 5,000 2016 10,000 17,500 20,000 2017 22,500 12,000 15,000 2018 20,000 25,000 15,000 2019 25,000 20,000 22,500
Total number of girls enrolled in all the three Universities together in the year 2015 is what percentage (%) of the total number of girls enrolled in University C in the year 2018?

Data Analysis: Girls Enrollment in Universities
This question requires us to analyze the provided table showing the year-wise enrollment of girls in three different Universities (A, B, and C) from 2015 to 2019 and then perform a percentage calculation based on the extracted data.
| Year | Number of girls in University A | Number of girls in University B | Number of girls in University C |
|---|---|---|---|
| 2015 | 15,000 | 10,000 | 5,000 |
| 2016 | 10,000 | 17,500 | 20,000 |
| 2017 | 22,500 | 12,000 | 15,000 |
| 2018 | 20,000 | 25,000 | 15,000 |
| 2019 | 25,000 | 20,000 | 22,500 |
Understanding the Question
We need to find out what percentage the total number of girls across all three universities (A, B, and C) in the year 2015 represents, compared to the number of girls specifically in University C in the year 2018.
Step-by-Step Calculation
Step 1: Find the total number of girls in all three Universities in 2015
From the table, the number of girls in 2015 are:
- University A: 15,000
- University B: 10,000
- University C: 5,000
Total girls in 2015 = Number of girls in A (2015) + Number of girls in B (2015) + Number of girls in C (2015)
Total girls in 2015 = \(15,000 + 10,000 + 5,000 = 30,000\)
Step 2: Find the number of girls in University C in 2018
From the table, the number of girls in University C in the year 2018 is 15,000.
Step 3: Calculate the required percentage
The question asks for the total number of girls enrolled in all three Universities together in the year 2015 as a percentage of the total number of girls enrolled in University C in the year 2018.
Percentage = \(\left( \frac{\text{Total girls in 2015}}{\text{Girls in University C in 2018}} \right) \times 100\%\)
Percentage = \(\left( \frac{30,000}{15,000} \right) \times 100\%\)
Percentage = \(2 \times 100\%\)
Percentage = \(200\%\)
Thus, the total number of girls enrolled in all three Universities together in the year 2015 is 200% of the total number of girls enrolled in University C in the year 2018.
Revision Table: Key Data Points
| Metric | Value | Year/University |
|---|---|---|
| Total Girls | 30,000 | A, B, C in 2015 |
| Girls in University C | 15,000 | University C in 2018 |
| Calculated Percentage | 200% | (Total 2015 / C 2018) * 100 |
Additional Information: Percentage Calculations in Data Interpretation
Percentage calculations are very common in data interpretation problems. They help in comparing quantities relative to each other. A percentage represents a part per hundred.
- To find what percentage 'A' is of 'B', you use the formula: \(\left( \frac{A}{B} \right) \times 100\%\).
- If 'A' is greater than 'B', the percentage will be greater than 100%, as seen in this problem where the total in 2015 (30,000) is greater than the number in C in 2018 (15,000).
- Understanding how to read tables and extract the correct values for comparison is crucial for solving such problems accurately.
