Understanding College Student Data
The question asks to find the college with the fewest female students with low income. We are given that all colleges have the same number of total students. We need to use the provided percentages and ratios.
Let 'T' be the total number of students in each college. Since 'T' is constant across all colleges, we can calculate the number of female students with low income for each college. For simplicity, we can assume T = 100 students per college to easily compare the results.
Calculating Female Students with Low Income
The number of female students with low income is determined by first finding the number of students with low income and then applying the male-to-female ratio for that group.
Formula:
$Number of Females (Low Income) = T * (Percentage Low Income / 100) * (Female Ratio Part / Total Ratio Parts)$
Assuming T = 100:
| College | % Students with Low Income | M:F Ratio (Low Income) | Low Income Students (T=100) | Female Proportion (Low Income) | Female Students with Low Income (T=100) |
| A | 35% | 6:7 | $100 \times \frac{35}{100} = 35$ | $\frac{7}{6+7} = \frac{7}{13}$ | $35 \times \frac{7}{13} \approx 18.85$ |
| B | 25% | 3:5 | $100 \times \frac{25}{100} = 25$ | $\frac{5}{3+5} = \frac{5}{8}$ | $25 \times \frac{5}{8} = 15.625$ |
| C | 24% | 1:2 | $100 \times \frac{24}{100} = 24$ | $\frac{2}{1+2} = \frac{2}{3}$ | $24 \times \frac{2}{3} = 16$ |
| D | 19% | 3:2 | $100 \times \frac{19}{100} = 19$ | $\frac{2}{3+2} = \frac{2}{5}$ | $19 \times \frac{2}{5} = 7.6$ |
| E | 15% | 5:3 | $100 \times \frac{15}{100} = 15$ | $\frac{3}{5+3} = \frac{3}{8}$ | $15 \times \frac{3}{8} = 5.625$ |
Comparing Results for Low Income Females
After calculating the number of female students with low income for each college (assuming T=100), we compare the values:
- College A: $\approx 18.85$
- College B: $15.625$
- College C: $16$
- College D: $7.6$
- College E: $5.625$
The smallest value among these represents the college with the least number of female students with low income.
