D is a set of multiples of 3.
400 is NOT a multiple of 3, hence none of its factors is a multiple of 3.

Therefore, those two sets won't have any overlap.

Answer: A.

A. 0
B. 1
C. 3
D. 5
E. 12


We see that D = {21, 24, 27, …, 99} and E = {1, 400, 2, 200, 4, 100, 5, 80, 8, 50, 10, 40, 16, 25}.

We have listed all the elements in E; however, since none of these elements is a multiple of 3, set D and set E have no numbers in common.

Answer: A
