Question

In a class of 25 students, the average score is 84. Six students in the class each recieved a max score of 100, and 3 students each recieved a score of 60. What is the average score of the remaining students?

Answer 1

84=sum/25
6(100)+3(60)+x=sum
find the sum from 1st equation then use it to find x in the 2nd question

Answer 2

I do not understand the first equation. sum of what?

Answer 3

sum of the marks for all the students in the class
average=sum of items/number of items
84=sum/25

Answer 4

Answer 6

are we together
here we multiply both sides by 25\[84=\frac{Sum}{25}\]
\[Sum=84*25=2100\]
