A) 5%
B) 17%
C) 16%
D) 13%
E) 30%
60-(x+16+z) + 50-(x+16+y) + 35-(z+16+y) + x + y + z +16 = 100   where x = people who bought MilkChicken   y = people who bought chickenApples   z= people who bought Milk and Apples   x+y+z= the number of people who bought just exactly two products.   Hence solving the above equation we get,   113 -(x+y+z) = 100   Thus, x+y+z= 13   Answer: 13%
