What will be the male population above poverty line for State P if the female population below poverty line for State P is 2.1 million?

Answer: Option D

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,
$$\begin{array}{rl}& 5:6=x:2.1\\ & \Rightarrow \frac{x}{2.1}=\frac{5}{6}\\ & \Rightarrow x=\frac{2.1\times 5}{6}\\ & \Rightarrow x=1.75\end{array}$$
∴ Population below poverty line for state P
= (2.1 + 1.75) million
= 3.85 million
Let the population above poverty line for state P be 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. So, the ratio of population below poverty line to that above poverty line for state P is 35 : 65.
$$\begin{array}{rl}& \therefore 35:65=3.85:y\\ & \Rightarrow y=\frac{65\times 3.85}{35}\\ & \Rightarrow y=7.15\end{array}$$
∴ Population above poverty line for state P = 7.15 million and so, male population above poverty line for state P
$$\begin{array}{rl}& =\left(\frac{6}{13}\times 7.15\right)\text{million}\\ & =3.3\text{ million}\end{array}$$
