Solution

The correct option is A Each statement alone is sufficient.
  1. From this, since of the passengers were company employees, then passengers were company employees. Then, since of the company employees were managers, so of the company employee were not managers. Therefore, company employees were not managers; SUFFICIENT.
  2. If 230 of the passengers were guests, then this represents of the cruise passengers. Therefore, there were 230 * 3 = 690 passengers altogether, 690 - 230 = 460 of whom were company employees. Since of the company employees were not managers, of the passengers who were company employees were not managers; SUFFICIENT.
  • The correct answer is D; each statement alone is sufficient.
