The two correct answers are:
B) Sixty percent of the women’s watches are digital watches. because there are 10 womens' watches, 6 of them are digital so that equals 60%.
and
D) There are more than twice as many men’s watches as women’s watches. because there are 21 mens' watches and 10 womens' watches. 10 x 2 = 20 < 21, so this is true also.
