If there are x consecutive even numbers that have a median of y, which of the following could be true?
I: y is even
II: x is even
III: y>x
A) I only
B) II only
C) II and III
D) I and III
E) I, II and III
The question stem asks which of the three statements COULD be true.
If we can find even ONE case in which a statement is true, then that statement COULD be true and must be included in the correct answer choice.
If x=2, then there are two consecutive even integers.
Let the two integers be 2 and 4.
y = median = (2+4)/2 = 3.
In this case, x is even and y>x.
Thus, the correct answer choice must include II and III.
Eliminate A, B, and D.
If x=3, then there are three consecutive even integers.
Let the three integers be 2, 4 and 6.
y = median = 4.
In this case, y is even.
Thus, the correct answer choice must include I.
Eliminate C.
The correct answer is
E.
