On the basis of given graph in question , we can see
Average prices of petrol in year 2014 = $ 73.70
And Average prices of Diesel in year 2014 = $ 66.79
Required Difference = Average prices of petrol in year 2014 - Average prices of Diesel in year 2014Correct Option: C
On the basis of given graph in question , we can see
Average prices of petrol in year 2014 = $ 73.70
And Average prices of Diesel in year 2014 = $ 66.79
Required Difference = Average prices of petrol in year 2014 - Average prices of Diesel in year 2014
Required Difference = $ (73.70 – 66.79) = $ 6.91
It is obvious from the graph.
