What will be the number of female above poverty line in the State S if it is known that the population of state S is 7 million?

Answer: Option B

Total population of state S = 7 million
∴ Population above poverty line
= {(100 - 19)% of 7} million
= (81% of 7) million
= 5.67 million
And so, the number of females above poverty line in state S
$$\begin{array}{rl}& =\left(\frac{3}{7}\times 5.67\right)\text{million}\\ & =2.43\text{ million}\end{array}$$
