{140, 270, 250, n}
Which of the following could be the median of the 4 integers listed above?
I. 170
II. 210
III. 240
Choose the most appropriate option.
A) I only B) II only C) I and II only D) II and III only E) I, II, and III
If 170 is the median, (n+250) / 2 = 170. Then n = 90. But n &lt; 140, so 170 can not be the median.   If 210 is the median, (n+250) / 2 = 210. Then n = 170. Thus 210 can be the median.   If 240 is the median, (n+250) / 2 = 240. Then n = 230. Thus 240 can be the median.   The answer is II and III only.
