This is not a question about Classical Music. It should get moved to Mathematics.

OK, let's try to do this step-by-step.
Alikers- 49 like A
Blikers - 53 like B
ABlikers - 27 like A & B
that means that there are 27 in common between Alikers and Blikers.
SO:
Alikers - 27 like B, therefore 22 do NOT like B
Blikers - 27 like A, therefore 26 do NOT like A
Get the process?
Keep doing this for all of the groups.
You should be able to use this process to calculate the answers to the questions.
