How many models have registered higher percentage increase in sales individually, as compared to the percentage increase in total sales?

Total percentage increase from 2010 to 2011,

= $$\frac{2884 - 2222}{2222} \times 100 = 29.79$$%

Percentage increase in sales of A,

= $$\frac{0.27 \times 2884 - 0.21 \times 2222}{0.21 \times 2222} \times 100 = 66.87$$%

Percentage of increase in sales of B,

= $$\frac{0.25 \times 2884 - 0.25 \times 2222}{0.25 \times 2222} \times 100 = 29.79$$%

Percentage of increase in sales of C,

= $$\frac{0.26 \times 2884 - 0.22 \times 2222}{0.22 \times 2222} \times 100 = 53.33$$%

Percentage of increase in sales of D,

= $$\frac{0.16 \times 2884 - 0.16 \times 2222}{0.16 \times 2222} \times 100 = 29.79$$%

Percentage of increase in sales of E,

= $$\frac{0.08 \times 2884 - 0.12 \times 2222}{0.12 \times 2222} \times 100 =$$ Some negative value 

Percentage of increase in sales of F,

= $$\frac{0.06 \times 2884 - 0.04 \times 2222}{0.04 \times 2222} \times 100 = 94.68$$%

Three models i.e A, C, F have registered higher percentage increase in sales individually.

Hence, option B is the correct answer.
