Correct Answer: 2400


Solution : Total population of C = 8000
Population above the poverty line in C = 80%
80% of C = $\frac{80}{100}\times8000$
= 6400
Number of females above the poverty line = $\frac{\text{Ratio of females above the poverty line}}{\text{Sum of the ratio of males and females above the poverty line }}\times$population above the poverty line
= $\frac{3}{8}\times6400$
= 2400
Hence, the correct answer is 2400.
