calculate Petrol/diesel car running per Km rate Assume the car runs 15 Km a litre Compare that with the electric car metre pls tell answer I will Mark as brainlist

Answer:
The fully considered well-to-wheel efficiency of a petrol powered car is equal to
The energy content of petrol (34.3 MJ/liter) minus the refinement & transportation losses (about 33% in India), multiplied by the km per liter.
So a regular petrol car giving 15 km/liter has an efficiency of 1/(34.3 divided by (100% minus 33%)) x 15 km/l = 0.29 km/MJ or 0.29 km/277 Wh
In other words, to travel a distance of 1 km, a small petrol car must expend 3.45 MJ or 955 Wh of energy.
Well-to-Wheel efficiency of a small Indian electric car
After observing data from users of the Mahindra e2o electric car, we find that on an average, an electric car in Indian road conditions consumes 90 Wh/km
We know that 1 Wh = 3600 J, so 90 Wh = 324,000 J. And the power plant efficiency, conversion and transmission losses in electricity in India are 70% or more.
So an Indian electric car @ 90 Wh/km has an efficiency of 1/(3600 divided by (100% minus 70%)) x 10^6 x (1/90) km/Wh = 0.93 km/MJ.
We then multiply this by the "The full cycle charge and discharge efficiency of the electric car". Let us take this factor as 80% for the e2o.
Then the final efficiency is 0.93 x 80% = 0.74 km/MJ or 0.74 km/277 Wh
