Analyzing Village Population Data
The question asks for the difference between the number of males and females in Village A, based on the provided table showing population distribution.
Understanding the Data for Village A
From the table, we have the following information for Village A:
- Total Population: 12,000
- Percentage Distribution:
- Males (M): 46%
- Females (F): Missing (-)
- Transgenders (T): 22%
Calculating the Missing Percentage for Females
The total percentage distribution for males, females, and transgenders in any village must add up to 100%. For Village A, we can calculate the percentage of females:
Percentage of Females = 100% - (Percentage of Males + Percentage of Transgenders)
Percentage of Females = $100\% - (46\% + 22\%)$
Percentage of Females = $100\% - 68\%$
Percentage of Females = $32\%$
Calculating the Number of Males and Females in Village A
Now that we have the percentages, we can calculate the actual number of males and females based on the total population of 12,000.
Number of Males = Percentage of Males $\times$ Total Population
Number of Males = $46\% \text{ of } 12,000$
Number of Males = $\frac{46}{100} \times 12000$
Number of Males = $0.46 \times 12000 = 5520$
Number of Females = Percentage of Females $\times$ Total Population
Number of Females = $32\% \text{ of } 12,000$
Number of Females = $\frac{32}{100} \times 12000$
Number of Females = $0.32 \times 12000 = 3840$
Calculating the Difference
The question asks for the difference between the number of males and females in Village A. This difference is calculated as:
Difference = Number of Males - Number of Females
Difference = $5520 - 3840$
Difference = $1680$
Thus, the difference between the number of males and females in Village A is 1680.
| Category | Percentage | Number |
|---|---|---|
| Total Population | 100% | 12,000 |
| Males | 46% | 5520 |
| Females | 32% | 3840 |
| Transgenders | 22% | 2640 |
| Difference (Males - Females) | - | 1680 |
Final Answer Verification
The calculated difference is 1680, which matches one of the provided options.
Revision Table: Population Distribution Concepts
| Concept | Explanation |
|---|---|
| Total Population | The entire number of people in a specific area (e.g., a village). |
| Percentage Distribution | How the total population is divided into different categories (e.g., gender, age) represented as a percentage of the total. |
| Calculating Number from Percentage | To find the actual number for a category, multiply the total population by the percentage (expressed as a decimal or fraction). For example, 46% of 12,000 is $0.46 \times 12000$. |
| Missing Percentage Calculation | If some percentages are given for categories that sum up to a total (like M, F, T summing to total population), the missing percentage is found by subtracting the sum of known percentages from 100%. |
Additional Information: Data Interpretation Skills
Solving problems like this requires careful data interpretation from tables. Key skills include:
- Reading table headers and rows accurately.
- Identifying the specific data points needed for the question (Village A population, M, F, T percentages).
- Understanding that percentages within a distribution category sum to 100%.
- Performing calculations involving percentages and whole numbers.
- Calculating differences or sums as required by the question.
Practice with different types of data representation (tables, charts, graphs) helps improve these skills, which are crucial for data analysis questions in exams.
