Question

Below is a Venn Diagram.

29 people are asked if they like action films or comedy films.
14 people said they liked action films.
17 people said they liked comedy films.
6 people said they liked action films but not comedy films.
Find the values of A, B and C

Answer 1

A = 8, B = 9 and C = 6.

Explanation:

We can create equations to solve this:

6 + A = 14

So A = 8.

A + B = 17

8 + B = 17

B = 9.

C = 29 - (6 + A + B)

= 29 - ( 6 + 8 + 9)

= 29 - 23

= 6.
