In a consumer survey, 80% of those surveyed liked at least one of three products: 1, 2, and 3. 50% of those asked liked product 1, 30% liked product 2, and 20% liked product 3. If 5% of the people in the survey liked all three of the products, what percentage of the survey participants liked more than one of the three products?
Select:  A) 5  B) 10  C) 15  D) 20  E) 25
pick 100 and x= all set with exactly two items   80=30+50+20 -(X)-10   X=10   so the answer is 10+5/100= 15%   answer 15
