The ratio of male to female in a class is 2:3. the career preference of the students in the class are to be represented in a circle graph. If the area of the graph allocated to each career preference is to be proportional to the number of students who have that career preference, how many degrees of the circle should be used to represent a career that is preferred by half of the males and half of the females in the class?
Choose the correct choice:
A) a)180 degree	B) b) 168 degree	C) c)191 degree	D) d)192 degree	E) e)204 degree
let the common ratio be x.. so M=2x and F=3x and Total=5x   1/2 of M= 2x/2 and 1/2 of F= 3x./2.   Total preferring that carrer =x+3x/2=5x/2..   Now 5x= 360, so x=360/5=72..   so 72*5/2=
