$8 、$ In Class One of Grade Five, there are 40 students. In the math exam, the average score of the top 8 students is 3 points higher than the class average, and the average score of the other students is $\qquad$ points lower than the average score of the top 8 students.
【Solution】Method 1: Since the average score of the top 8 students is 3 points higher than the class average, it can be inferred that they provide $3 \times 8=24$ points to the other students. Without these 24 points, the average score of the other students would be $24 \div (40-8)=0.75$ points lower than the class average. Therefore, the average score of the other students is 3.75 points lower than that of the top 8 students. Method 2: Let the average score of the top 8 students be $x$, then the class average score is $x-3$. Let the average score of the other students be $y$. We can set up the equation: $8 x+32 y=40(x-3)$
Solving for: $32 x-32 y=120 \Rightarrow x-y=3.75$
That is, the average score of the other students is 3.75 points lower than that of the top 8 students.
