conversations.value: Being women half of the guests, there were 50/2 = 25 women in the movie screening.
  Adding the 15 men to the number of women guests, there were 25 + 15 = 40 men and women.
  From a total of 50 guests, 50 - 40 = 10 were children.
  Knowing 1/5 of the men left, 15/5 = 3 men left.
  Thus, 3 men + 4 children = 7 people left in all.
  Therefore, 50 - 7 = 43 people stayed.
