B Correct answer
Explanation

Total population of State B is 7,200. The population below poverty line is 25% of 7,200, which is 1,800. The ratio of males to females below poverty line is 3:5, so females are 5/(3+5) = 5/8 of 1,800. 1,800 * (5/8) = 1,125.

AI explanation

Calculate the total population below the poverty line in State B as 25% of 7,200, which equals 1,800. Based on the 3 to 5 proportion of males to females below the poverty line, there are 5 females out of 8 total people in this group. The number of females is 1800 multiplied by 5 divided by 8, which results in 1,125.
