Understanding the Data Table
The question asks us to analyze the provided table, which contains data on the population distribution by men, women, and children, as well as the percentage of overweight individuals within each category, across different years from 2016 to 2021. We need to focus specifically on the data for the year 2018 to answer the question.
Calculating Overweight Population in 2018
To find the difference between the number of overweight women and overweight children combined and the number of overweight men in the year 2018, we first need to calculate the exact number of overweight individuals in each category for that year.
| Category | Total Population (2018) | Percentage Overweight (2018) |
|---|---|---|
| Men | 31500 | 30% |
| Women | 30000 | 25% |
| Children | 6000 | 35% |
Let's calculate the number of overweight individuals for each category in 2018:
- Overweight Men in 2018:
The number of men in 2018 is 31500, and 30% of them are overweight.
Number of overweight men = $\text{30% of } 31500$
Number of overweight men = $\frac{30}{100} \times 31500$
Number of overweight men = $0.30 \times 31500 = 9450$
- Overweight Women in 2018:
The number of women in 2018 is 30000, and 25% of them are overweight.
Number of overweight women = $\text{25% of } 30000$
Number of overweight women = $\frac{25}{100} \times 30000$
Number of overweight women = $0.25 \times 30000 = 7500$
- Overweight Children in 2018:
The number of children in 2018 is 6000, and 35% of them are overweight.
Number of overweight children = $\text{35% of } 6000$
Number of overweight children = $\frac{35}{100} \times 6000$
Number of overweight children = $0.35 \times 6000 = 2100$
Finding the Difference in Overweight Population (2018)
The question asks for the difference between the number of overweight women and overweight children together and the number of overweight men in 2018.
First, let's find the combined number of overweight women and children in 2018:
Overweight women + Overweight children = $7500 + 2100 = 9600$
Now, we find the difference between this combined number and the number of overweight men in 2018:
Difference = (Overweight women + Overweight children) - Overweight men
Difference = $9600 - 9450 = 150$
The difference between the number of overweight women and overweight children together and the number of overweight men in the year 2018 is 150.
Revision Table - Data Interpretation
| Year | Men (Overweight) | Women (Overweight) | Children (Overweight) | Overweight Women + Children | Difference (W+C) - M |
|---|---|---|---|---|---|
| 2018 | 9450 | 7500 | 2100 | 9600 | 150 |
Additional Information - Percentage Calculations
Calculating a percentage of a number is a fundamental skill in data interpretation. To find 'X% of Y', you can use the formula:
Result = $\frac{X}{100} \times Y$
Alternatively, you can convert the percentage to a decimal by dividing by 100 (e.g., 30% = 0.30) and then multiply by the number:
Result = (Decimal equivalent of X%) $\times Y$
This technique was used repeatedly in the solution to find the number of overweight individuals in each category for the year 2018.
