  use formula.... n(AUB)=n(A)+n(B)-n(A^B)
  ^ = intersection
  255=200+115-x
  x=60

• P(AUB)=255;P(A)=200-P(A^B);P(B)=115-P(A^B);
  P(AUB)=P(A)+P(B)-P(A^B);
  P(A^B)=20

• question needs correction.
  200 out of total 255 like pizza,.....(in case ans=60)
  or 200 out of 155 like pizza,.....(in case ans=70)
  without correction(no solution)
  but some guys give ans=170 which is not possible because persons like burger and pizza both always less then 115. hope u smart enough to understand..
