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.
If the male population above poverty line for State R is 1.9 million, then the total population of State R is?
4.5 million
4.85 million
5.35 million
6.25 million
Correct answer is D
Let the total population of State R be x million.
Then, population of State R above poverty line
= [(100 - 24)% of x] million
= ( 76/100 x x ) million
And so, male population of State R above poverty line
= [ 2/5 x ( 76/100 x x ) ] million
But, it is given that male population of State R above poverty line= 1.9 million.
Therefore 2/5 x ( 76/100 x x ) = 1.9 => x = (5 x 100 x 1.9)/76 x 2 = 6.25
Therefore Total population of State R = 6.25 million.
