You must have seen and heard many incidents of cheating at petrol pumps or such an incident must have happened to you too. While filling petrol, we only check zero and assume that we have not been cheated. But it is not so. While filling petrol, apart from zero, you should also check its density.
While filling petrol-diesel, not only ‘0’ on the meter, also check the density, all the fun happens here.
