Correct Answer: 1,125
Solution :
According to the question:
Total population of state B = 7,200
The percentage of the population below the poverty line of state B = 25%
Population below the poverty line = $7200\times\frac{25}{100} = 1800$
The proportion of males and females below the poverty line in state B = 3 : 5
$\therefore$ No. of females = 1800$\times \frac{5}{8}$ = 1125
Hence, the correct answer is 1,125.
