If the total population of town C is 8000 then what is the number of females above the poverty line in state C?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2400.
Given that
If the total population of town C is 8000
The percentage of population below the poverty line of town C = 20 %
So, the population above the poverty line of town C = 8000 × 80/100 = 6400
The ratio of male and female of population above the poverty line of town C = 5 : 3
Hence, the number of females above the poverty line in town C = 6400 × 3/8 = 2400
