I will go with C) I AND II only


n could be arranged following ways(since we dont know the value of n)

1) 150,200,250,n

In this case median = 225 (not one of the chopices given)

2) n,150,200,250

median = 150+200/2 = 175 (could be)

3) 150,n,200,250


median will be between n and 200 (we have already considered 175 and 215 and 235 will not be in this case)

4) 150,200,n,250 (215 could be if n =230 its possible)



Since the question says could be I will go with I and II

Whats the OA?
