As 85% of those surveyed liked at least one of three products then 15% liked none of three products.
Total = {liked product 1} + {liked product 2} + {liked product 3} - {liked exactly two products} - 2*{liked three product} + {liked none of three products}
\(100=50+30+20-x-2*5+15\) --> \(x=5\), so 5 people liked exactly two products. More than one product liked those who liked exactly two products, (5%) plus those who liked exactly three products (5%), so 5 + 5 = 10% liked more than one product.
Answer: B.
