Answer 5

90 were interested in an interview show and a documentary, but not reruns.
(i n d) - c = 90

12 were interested in an interview show and reruns but not a documentary.
(i n r) - d = 12

42 were interested in reruns but not an interview show.
i - r = 42

72 were interested in an interview show but not a documentary.
i - d = 72

30 were interested in a documentary and reruns.
r n d = 30

18 were interested in an interview show and reruns.
r n i = 18

24 were interested in none of the three.
u - i - r - d = 24


find: i - r - d
find: r - i - d
find: d - i - r
