Question
Private vehicles travelled in 2011 are approximately
what percent less than the Private vehicles travelled in 2013? Study the following information carefully and answer the given questions: The table shows the total number of vehicles travelled and difference between the number of Public vehicles and Private vehicles travelled in the given five years. Total Vehicles = Public + PrivateSolution
Public vehicles travelled in 2011 = (850+250)/2 = 550 Private vehicles travelled in 2011 = 850 – 550 = 300 Public vehicles travelled in 2013 = (1100+400)/2 = 750 Private vehicles travelled in 2013 = 1100 – 750 = 350 Required % = [(350 – 300)/350] × 100 = 14% approx.
