The following pie charts give the details of the number of different models of motorcycles sold in two consecutive years.



Total = 7 lakh


Total = 8.4 lakh

Models:

Additional data for questions 5:

In 2015, if the sales of Maestro model of Wonder motorcycles is 25% more than that in 2014, then what is the percentage increase in the sales of CT 100 model of Wonder motorcycles from 2013 to 2015?
Options:

D) 68%
E) None of these
Solution:

The sales of Maestro model of Wonder motorcycles in 2015 = \(\cfrac{8.4×28}{100}× 1.25 \)  = 2.94 lakh 

The sales of CT100 model of Wonder motorcycles sold in 2015 = 2.94 \(× \cfrac{20}{25}\)  = 2.352 lakh

∴The required percentage increase = \(\cfrac{2.352-1.4}{1.4}\) × 100 = 68%
