One of the most popular questions when it comes to buying a car is 'Kitna deti hai’? (What is the mileage of the car?)
Fuel efficiency of the car is calculated as the distance travelled per unit volume of fuel consumed. During heavy traffic the mileage of your car will be less as compared to empty roads.

Better fuel efficiency would mean higher savings while poor fuel efficiency would mean higher expenses.
Here's a lesson on ‘Earnings Per Share’ that draws a similar analogy to fuel efficiency
