Indian Institute of Foreign Trade 2012 Solved Paper

The number of Figos sold in 2010 $=80000\times \frac{9}{100}=7200$
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$=100000\times \frac{44}{360}=12222$
We can calculate the number of cars sold for the remaining cars too and the result is tabulated as shown below:-

	2010	2011	Growth
Figo	7200	12222	69.75%
Alto	25600	30833	20.44%
Alto	19200	18611	-3.06%
I10	16800	22777	35.58%
Honda City	11200	15555	38.88%

Thus, we can see that 3 models have grown more than the average growth rate(of 25%) for all the models taken together.
Hence, option B is the correct answer.
