Alpha and Beta, two friends were both planning to buy a car. They listed down 20 features which they were looking for. They both evaluated all the prospective cars with the listed features using their individual scoring schemes.
Alpha gave a zero score to each feature missing in the car, score of 2 for each feature available and an additional score of 3 if he was happy with the feature.
Similarly, Beta gave a score of -3 to each feature missing in the car, score of 1 for each feature available and an additional score of 6 if he was happy with the feature.
They added the scores of features to arrive at the final score for each car.
