During which of the following years number of employees working in production deptt. of the factory was less than 50% of the total employees of the factory?

It is clear from the table that it was the year 2007 when the number of employees working in each department was more than that in the previous year and nearly equal to next year.

According to the table in the research and development department number of employees remained nearly same during the year from 2003 to 2008.

It is clear from the table that none of the state has the production of rice increased continuously over the years.

Production of rice in different years by all states together:
2000 ? 1500 + 1250 + 1160 + 1520 + 1440 + 1600 = 8470 tonnes
2004 ? 1480 + 1190 + 1190 + 1500 + 1350 + 1620 = 8330 tonnes
2005 ? 1620 + 1400 + 1310 + 1480 + 1430 + 1510 = 8750 tonnes
2006 ? 1700 + 1450 + 1300 + 1590 + 1280 + 1610 = 8930 tonnes
2007 ? 1540 + 1320 + 1340 + 1630 + 1380 + 1580 = 8790 tonnes
2008 ? 1650 + 1380 + 1360 + 1580 + 1400 + 1590 = 8960 tonnes
Hence, in year 2008 the production of rice was the highest.

Average quantity of rice produced by state D = 9300/6 = 1550 tonnes
Average quantity of rice produced by state F = 9510/6 = 1585 tonne
Hence, required ratio = 1550 : 1585 = 310 : 317

Production

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.

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,

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

Required difference = Number of units ( In 2003 - In 2005 )
Required difference = 112 - 78 = 34 crores
