Answer:


I am currently unable to draw the Venn diagrams but this is the best I can suggest.
n(U) = 56%
n(F) = 48%
n(B) = 42%.
Given n(U N F) = 30%.

We have to find n(B - n(B N n(U U F))).
First find n(U U F) = n(U) + n(F) - n(U N F) = 74%.
Then n(B U n(U U F) = n(B) + n(U U F) - n(B N n(U U F)) = 100, since all respondents participated in the survey. This will give n(B N n(U U F)) = 16%.
Finally, n(B - n(B N n(U U F))) = 42 - 16 = 26%. Of 1200 respondents, this number comes exactly to 312.

A is the answer.
