In the bar graph shown here, the ratio of 'Exchange-traded funds (Commodity)' to 'Exchange-traded funds (Fixed Income)' was highest for which of the following years?
Just by observation, you can be sure that 2008 can be eliminated. Now among 2010 and 2011, the 'Equity' part is same for both of them. To have a higher ratio value, the 'commodity' part should be higher and 'Fixed Income' part should be lower. Thus among these two years, we can again eliminate 2011. The following table will give you the approximate value for years 2009 & 2010.
