Sum of all the percentages is 105 but we know that percentages cannot exceed more than 100, so from where this extra 5 percentage comes from, it comes out because we counted the people who have both phones and cars, in the question we already know that 2000 families have both so from here we can conclude that here are 40,000 families in the town. From here we can easily find the rest of the answer.
