B.19
C.25.5
D.cannot be determined​

Answer 1

Answer:

Now, in the former set of 27 observations, 18 is the value of the 14th element in the ascending/descending list of these observation values (By definition of Median). If, the above three values are added to the list, 16 would fall before 18 and 50 would fall after 18 in the list.
