The intent of the problem seems to be that Z = L^M, as shown in red below:
sachin_yadav wrote:Set A consists of integers {3, -8, Y, 19, -6} and Set B consists of integers {K, -3, 0, 16, -5, 9}. Number L represents the median of Set A, number M represents the mode of set B, and number Z = L^M. If Y is an integer greater than 21, for what value of K will Z be a divisor of 26?
(A) -2
(B) -1
(C) 0
(D) 1
(E) 2
The MODE of a set is the value that appears the GREATEST NUMBER OF TIMES.
For Set B to have a mode -- for one of the values of Set B to appear more than any other value in set B -- K must be equal to one of the 5 values already present:
-3, 0, 16, -5, 9.
Of the 5 answer choices, only
C -- K=0 -- is included in the list above.
The correct answer is
C.
