In a certain business school class, p students are accounting majors, q students are finance majors, r students are marketing majors, and s students are strategy majors. If pqrs = 2145, and if 1< p < q < r < s, how many students in the class are marketing majors?  Choices:
A) 3
B) 5
C) 8
D) 11
E) 17
pqrs = 2145 = 3 * 5 * 11 * 13   Since 1&lt; p &lt; q &lt; r &lt; s, the number of students who are marketing majors is r = 11.   The answer is 11.
