Answer:
Step-by-step explanation:
The intersection point (centroid) divides the medians in ratio 2:1. it does mean that the long segment value is the short segment value multiplied by two. let's call the centroid point G.
BG=DG*2=4*2=8
CG=EG*2=2*2=4
AG=FG*2 =>FG=AG/2=6/2=3
Step-by-step explanation:
Let a be the total score of Div. A
Let b be the total score of Div. B
given,

as equation 1.
and

as equation 2.
Now multiply equation 2 by 1/20 to eliminate b to solve for a.

take this new equation as equation 3.
now we will use equation 1 + equation 3 to eliminate b to solve for a.

Div.A total score = 600
Average Score = Total Score / Number of students.
