Solution:
A) Company A’s total sales decreased over the 2-year period from 2009 to 2011.--> True---If the Total sales for 2009 was 100, in 2010 it was 110 and in 2011 it was 110-11=99. Therefore, there was an overall decrease in the two year period
B) Company B’s total sales increased by a higher percentage over the 2-year period than any of the other company’s.-->True---Because Company B is the only company whose % change is positive for both year rest for all the companies it is at least negative for 1 year. Note we are asked about percentages and not about figures. Thus, this is true.
C) At Company C, the ratio of total sales in 2011 to total sales in 2009 was 112:100, or 28:25. --> False--If the sale for 2009 was 100 then for 2011 it will be 111.15. Thus the Ratio= 111.15:100
IMO A & B
Hope this helps!
