2004=800+500+475=1775Total automobile production in the year
2005=700+550+450=1700Total automobile production in the year
2006=1025+675+475=2175Total automobile production in the year
2007=1200+650+475=2325Total automobile production in the year
2008=1250+600+350=2200Total domestic sales of automobiles in the year
2004=(700+450+300)=1450Total domestic sales of automobiles in the year
2005=(675+500+350)=1525Total domestic sales of automobiles in the year
2006=(900+625+400)=1925Total domestic sales of automobiles in the year
2007=(1050+600+375)=2025Total domestic sales of automobiles in the year
2008=(975+550+350)=1875In the year 2005 and 2008 the production and sales respectively are not increasing absolutely. Hence, we will check only for the year 2006 and 2007
The ratio between absolute increase in domestic sales in the year 2006 over the year 2005 and absolute increase in production in the year 2006 over the year
2005==0.84Similarly, the required ratio for year 2007
==0.66Hence, we can say that the ratio is the highest for the year 2006. Therefore, option B is the correct answer
