In a consumer survey, 85% 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 7% 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 answers
A) 5	B) 8	C) 15	D) 20	E) 25
Use the forumla ;   Total = Group1 + Group2 + Group3 - (sum of 2-group overlaps) - 2*(all three) + Neither   100 = 50 + 30 + 20 - ( sum of 2) -2(7) +15   100 = 101-( sum of 2)   1 = sum of 2   so more than 1 = 8   8
