For State Q:

Male population below poverty line = 2.4 million.

Let the female population below poverty line be x million.

Then, 3 : 5 = 2.4 : x         x =	5 x 2.4	= 4.
	3

Total population below poverty line = (2.4 + 4) = 6.4 million.

If N_q be the total population of State Q, then,

25% of Nq = 6.4 million         Nq =		6.4 x 100		million = 25.6 million.
		25

For State T:

Male population below poverty line = 6 million.

Let the female population below poverty line be y million.

Then, 5 : 3 = 6 : y         y =	3 x 6	= 3.6.
	5

Total population below poverty line = (6 + 3.6) = 9.6 million.

If N_t be the total population of State T, then,

15% of Nt = 9.6 million         Nt =		9.6 x 100		million = 64 million.

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	= 1.75.
	6

Population below poverty line for State P = (2.1 + 1.75) million = 3.85 million.

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.

35 : 65 = 3.85 : y         y =	65 x 3.85	= 7.15.
	35

Population above poverty line for State P = 7.15 million and so, male population above poverty line for State P

=		6	x 7.15		million
		13

    = 3.3 million.

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

=		3	x 5.67		million
		7

    = 2.43 million.

Let the total population of State R be x million.

Then, population of State R above poverty line

    = [(100 - 24)% of x] million

=		76	x x		million
		100

And so, male population of State R above poverty line

=		2	x		76	x x			million
		5			100

But, it is given that male population of State R above poverty line = 1.9 million.

	2	x		76	x x		= 1.9         x =	5 x 100 x 1.9	= 6.25.
	5			100				76 x 2

Total population of State R = 6.25 million.

Total number of Operators who left the Company during 1995 - 2000

    = (104 + 120 + 100 + 112 + 144)

    = 580.

Total number of Operators who joined the Company during 1995 - 2000

    = (880 + 256 + 240 + 208 + 192 + 248)

    = 2024.

Required Percentage =		580	x 100		% = 28.66% 29%.
