What is the difference between number of units (in crores) sold by company D in the year 2003 and the year 2005?

In 2007 , the average number of units sold (in crores) = Units sold of ( Company A + Company B + Company C + Company D + Company E + Company F ) / Total number of companies
In 2007 , the average number of units sold (in crores) = (152 + 69 + 96 + 135 + 140 + 176)/6 = 768)/6 = 128

The number of units sold by the company over the years:
Company A ? Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )
Company A ? 110 + 118 +143 + 126 + 152 + 195 = 844
Company B ? Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )
Company B ? 91 + 93 + 85 + 99 + 69 + 35 = 472
Company D ? Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )
Company D ? 112 + 166 + 78 + 83 + 135 + 198 = 772
Company F ? Units sold ( In 2003 + In 2004 + In 2005 + In 2006 + In 2007 + In 2008 )
Company F ? 64 + 56 +120 + 70 + 176 + 54 = 540
Hence, company B has sold the maximum number of units over the years,

Total number of employees in 2003 = Employees of (Production deptt.+ Sales deptt.+ Procurement deptt.+ Administration & Accounts deptt. + Research & Development deptt.)
Total number of employees in 2003 =150 + 25 + 50 + 45 + 75 = 345
Total number of employees in 2005 = (Production deptt.+ Sales deptt.+ Procurement deptt.+ Administration & Accounts deptt.+ Research & Development deptt.)
Total number of employees in 2005 = 450 + 65 + 30 + 90+ 73 = 708
Hence, it was the year 2005 when total number of employees in the factory became nearly double the total number of employees working in the factory during 2003.

Production

Number of total employees in 2003 = 150 + 25 + 50 + 45 + 75 = 345
? Percentage number of employees working in production deptt . = 150 x 100/345 = 43.48%
Number of total employees in 2004 = 225 + 40 + 45 + 62 + 70 = 442
? Percentage number of employees working in production deptt. = 225 x 100/442 = 50.9%
Number of total employees in 2005 = 450 + 65 + 30 + 90+ 73 = 708
? Percentage number of employees working in proudction deptt. = 450 x 100/708 = 63.56%
Total number of employees in 2006 = 470 + 73 + 32 + 105 + 70 = 750
? Percentage number of employees working in production deptt. = 470 x 100/750 = 60.67%
Total number of employees in 2007 = 500 + 80 + 35 +132 + 74 = 821
? Percentage number of employees working in production deptt, = 500 x 100/821 = 60.9%
Total number of employees in 2008 = 505 + 75 + 36 + 130 + 75 = 821
? Percentage number of employees working in production in deptt. = 505 x 100/821 = 61.5%
Hence, it is clear that percentage number of employees working in production deptt. was less then 50% in 2003

In 2005, total number of units sold by all the companies = Total number of units sold by ( Company A + Company B + Company C + Company D + Company E + Company F )
In 2005, total number of units sold by all the companies = 143 + 85 + 100 + 78 + 154 + 120 = 680
Hence, required percentage = Number of units sold by company B x 100/ Total number of units sold by all the companies in 2005
Hence, required percentage = 85 x 100 /680 = 12.5%

Total number of units sold by company A over the years = 110 + 118 + 143 + 126 + 152 + 195 = 844
Total number of units sold by company C over the years =103 + 153 + 100 + 128 + 96 + 56 = 636
Total number of units sold by company D over the years = 112 + 166 + 78 + 83 + 135 + 198 = 772
Total number of units sold by company E over the years = 72 + 169 + 154 + 98 + 140 + 192 = 825
Hence, company A has sold the maximum number of units over the years.

According to question,
The population of males below poverty line in State B = 500
As per given graph,
Proportion of Male and Female below poverty line in State B = 5 : 7
If 5 Male below poverty line then total population will be 12 in State B
If 1 Male below poverty line then total population will be 12/5 in State B
If 500 Male below poverty line then total population will be 12 x 500 / 5 in State B
Population of State B below poverty line = 500 x 12 / 5 = 100 x 12 = 1200
Percentage population below poverty line in State B = 15 % ( As given in table chart)
? Total population of State B = 1200 x 100 / 15 = 80 x 100 = 8000

As per given question,
Percentage population below poverty line = 12 %
Percentage population above poverty line = ( 100 - 12 ) % = 88 %
Proportion of male and female above poverty line = 4 : 3
The total population of state A = 3000
The population above poverty line in state A = 3000 x 88 %
Number of females above poverty line in State A = 3000 x 88 % x 3 / 7 ? 1200.

Since we cannot find the population of States C and D separately, we cannot find the required value.
