The ratio of boys to girls 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 one third of the boys and two-third of the girls in the class?
Choose the correct answer:
A) a)160 degree  B) b) 168 degree  C) c)191 degree  D) d)272 degree  E) e)192 degree
let the common ratio be x.. so B=2x and G=3x and Total=5x   1/3 of M= 2x/3 and 2/3 of F= 2x..   Total preferring that carrer = 2x/3+2x=8x/3..   Now 5x= 360, so x=360/5=72..   so x*8/3= 72*8/3=

<output>192</output>
192   ans 192   e)192 degree
<result>E</result>
