Study the following pie charts regarding to sales of 5 models of cars for the years 2010 and 2011, and answer the question
If the 2010 sales for all car models is 80,000 and these have grown by 25% in 2011, then how many models have grown more than the average growth rate for all the models taken together?
The number of Figos sold in 2010 = 80000*9/100 = 7200
The total number of cars sold increase by 25% and thus, total number of cars in 2011 = 100000
Thus, the total number of Figos sold in 2011 = 100000*44/360 = 12222
We can calculate the number of cars sold for the remaining cars too and the result is tabulated as shown below:-
