A: 49
B:45
C: 20.1
D:114
(3x-11)+(6x-10)+x=180

Answer:
The student whose marks between quarter grades & topic tests score has maximum proportionate deviation
Step-by-step explanation:
Percentage change shows the proportionate change in a value, from the initial point. Formula = ( Change / Old ) x 100
Percentage change in students' quarter grades from topic tests score =
[ ( Quarter topic test score - Topic test score ) / Topic Test score ] x 100
Eg : Quarter Grade = 80, Test score = 60.
Percentage change = [ (80 - 60)/ 60 ] x 100 = ( 20 / 60 ) x 100 = 33%
So, student who has this maximum proportionate or percentage deviation between quarter grades & topic tests score - that student change would be represented by the point farthest from 0 on a number line.
