A)20%
B)33%
C)40%
D)50%
E)67%
Let the total number of people = 100.
Since 60% like basketball, the number who like basketball = (60/100)(100) = 60.
Since 30% like both basketball and golf, the number who like both = (30/100)(100) = 30.
Implication:
Of the 60 people who like basketball, 30 also like golf.
Thus:
(total who like both)/(total who like basketball) = 30/60 = 1/2 = 50%.
The correct answer is
D.
