D is the set of all the multiples of 3 between 20 and 100. E is the set of all the factors of 400. Set D and Set E have how many numbers in common? Choose the correct choice from the following choices.
A) 0	B) 1	C) 3	D) 5	E) 12
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.   0nswer: 0.
