What was the ratio of the combined sales of the two highest selling models to that of the two lowest selling models in 2011?

Solution

Two highest selling models in 2011 = (27% + 26%) of 2884

Two lowest selling models in 2010 = (8% + 6%) of 2884

Their ratio = (27% + 26%) of 2884 : (8% + 6%) of 2884

= 53% of 2884 : 14% of 2884

= 53 : 14

= 4 : 1 (approx)

Hence, option D is the correct answer.
