Question

• A. $2.1million$
• B. $2.3million$
• C. $2.7million$
• D. $3.3million$

Answer 1

Answer: (D)

$3.3million$

Female population below poverty line for State $P=2.1$ million
Let the male population below poverty line for State P be x million.
Then, $5:6=x:21\Rightarrow x=\frac{2.1\times 5}{6}=1.75$.
$\therefore$ Population below poverty line for State $P=(2.1+1.75)million=3.85million$.
Let the population above poverty line for State P by y million.
Since, $35$% of the total population of State P is below poverty line, therefore, 65% of the total population of State P is above poverty line i.e., the ratio of population below poverty line to that above poverty line for State P is $35:65$.
$\therefore 35:65=3.85:y\Rightarrow y=\frac{65\times 3.85}{35}=7.15$.
$\therefore$ Population above poverty line for State $P=7.15$ million and so, male population above poverty line for State P
$=(\frac{6}{13}\times 7.15)million$
$=3.3million$.
