I used a venn diagram.
Left circle = Art @ 15%. right circle = Music at 10%
(1) tells us 2/3 of the students who are enrolled in an art class (10% of total Population) are also enrolled in a music class. This means that the all of students enrolled in music are also enrolled in an art class. Sufficient.
(2) Doesn't tell us anything about the relationship between the 2 classes. In sufficient.
Of the students in a certain school, 15 percent are nrolled in an art class and 10 percent are enrolled in a music class. What percent of the students in the school are enrolled in neither an art class nor a music class?
(1) 2/3 of the students who are enrolled in an art class are also enrolled in a music class.
(2) There are more than 100 students in the school.
Please don't forget the detailed explanation. Very very important
