In a consumer survey, 90% 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?  Choose the correct choice from the following choices.
A) 5 B) 10 C) 15 D) 20 E) 25
pick 100 and x= all set with exactly two items   90=30+50+20 -(X)-10   X=0   so the answer is 0+5/100= 5%   5nswer 5
