College C Students Without Low Income Calculation
First, determine the percentage of students in College C who do not belong to the low-income group.
- Percentage of students with low income = 24%
- Percentage of students without low income = 100% - 24% = 76%
Calculate Total Students Without Low Income
Next, calculate the actual number of students without low income using the total student count for College C.
- Total students in College C = 5000
- Number of students without low income = $ \frac{76}{100} \times 5000 $
- Number of students without low income = $ 0.76 \times 5000 = 3800 $
Determine Number of Males Without Low Income
Finally, use the proportion of males and females without low income to find the number of males.
- Proportion of males to females without low income = 2:3
- The total parts in this proportion is $ 2 + 3 = 5 $.
- Males constitute $ \frac{2}{5} $ of the students without low income.
- Number of males without low income = $ \frac{2}{5} \times 3800 $
- Number of males without low income = $ 2 \times 760 = 1520 $
Therefore, there are 1520 males without low income in College C.
