Set A consists of the numbers {1, 4, 9, 9, 12}. Set B consists of the numbers {1, 6, 8, 12}. If Set C is formed by combining Sets A and B, which of the following expressions give the relationship between the medians of sets A, B, and C?
A. B = C and C > A
B. A < B < C
C. B < A < C
D. B < C < A
E. A = C and C > B
A. B = C and C > A
B. A < B < C
C. B < A < C

Bunuel
A = {1, 4, 9, 9, 12} Median (A) = 9
B = {1, 6, 8, 12} Median (B) = \(\frac{(6+8)}{2} = 7\)
Combining sets is taking the Union. (All elements of both sets form the new set C)
C = {1, 1, 4, 6, 8, 9, 9, 12} Median (C) = 8
Hence Median of : B < C < A
Option (D) is out answer.
