As per the given pie chart in question ,
The corresponding angle of year 2012 = 105°
The corresponding angle of year 2011 = 75°
Total Increase = 105° - 75° = 30°Percentage increase = 
Total Increase 
× 100 The corresponding angle of year 2011 Percentage increase in 2012 in comparison to 2011 = 3000 = 40 75
The corresponding angle of year 2013 = 135°
The corresponding angle of year 2012 = 105°
Total Increase = 135° - 105° = 30°Percentage increase = Total Increase × 100 The corresponding angle of year 2012
Correct Option: B

The corresponding angle of year 2013 = 135°
The corresponding angle of year 2012 = 105°
Total Increase = 135° - 105° = 30°Percentage increase = Total Increase × 100 The corresponding angle of year 2012 Percentage increase in 2013 in comparison to 2012 = 3000 = 200 105 7
Required ratio = Percentage increase in 2012 in comparison to 2011 : Percentage increase in 2013 in comparison to 2012∴ Required ratio = 40 : 200 = 7 : 5 7
