The following table gives the percentage distribution of population of five states, P, Q, R, S and T on the basis of poverty line and also on the basis of sex.
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?
2.1 million
2.3 million
2.7 million
3.3 million
Correct answer is 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, 5 : 6 = x : 21 => x = (2.1 x 5)/6 = 1.75
Therefore 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 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 => y = (65 x 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
= ( 6/13 x 7.15 ) million
= 3.3 million
