Review: Company Awards Ceremony
Explanation
In this question, we have company members, who include
so-called managers and non-managers, and event staff. On to the data
statements, separately first.
Statement (1) gives us the total number of attendees. This
number times
will give us
the number of employees,
, and that number
times
will be the
number of non-managers. So we can determine the number of non-managers
uniquely. Statement (1) is sufficient.
Statement (2) gives us the number of staff. Since
of the total
are staff, we can form an equation.
and thus solve for the total number. By the logic discussed
for Statement (1), having the total number of attendees is sufficient.
Therefore, Statement (2) is sufficient.
The correct answer is (D).
