**Question: 378**

**4.** Twenty students in a chemistry class took a test on which the overall average score was 75. If the average score for 12 of those students was 83, what was the average score for the remaining members of the class?

A. 60

B. 61

C. 62

D. 63

E. 64

**Correct Answer:** D

**Explanation:**

**D** If 20 students scored an average of 75 points, then the sum of their scores is total points.

If 12 of those students scored an average of 83 points, then the sum of their scores is points.

Therefore, the remaining 8 students scored points altogether, so their average score is points.
