D is the set of all the multiples of 3 between 20 and 100. E is the set of all the factors of 200. Set D and Set E have how many numbers in common? Pick
A) 10
B) 1
C) 3
D) 5
E) 0
D is a set of multiples of 3.   200 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: 0.
