Options.
A) 52 B) 50 C) 54 D) 55 E) 56
I came up with the same answer choice B, but my approach was slightly different!   50% were employees which shall cover those who were only employees and those who were both shareholders and employees.   Thus, the number of attendants who were only shareholders is 100% - 50% = 50%.  100  - 50=
