A local television sends out questionnaires to determine if viewers would rather see a documentary, an interview show, or reruns of a game show. There were 300 responses with following results:

A 90 were interested in an interview show and a documentary but not reruns.

B 12 were interested in an interview show and reruns but not a documentary.

C 42 were interested in reruns but not an interview show.

D 72 were interested in an interview show but not a documentary.

E 30 were interested in a documentary and reruns

F 18 were interested in an interview show and reruns.

G 24 were interested in none of the three.

How many are interested in exactly one kind of show?

I thought 42+72=114 would be the answer because it's one kind of show, and I tried the Venn Diagram but it won't make any sense because of the crazy data.

Thanks for your help in advance.

PS: Would absolutely love an explained answer.
