Question #N784
A group of 10 students took a test, and the average score on the test was 70. If one student scored 100 on the test, what was the average score of the other 9 students?
A. 65
B. 68
C. 70
D. 72
Correct Answer is: B
The total score of all 10 students is 10 * 70 = 700. If one student scored 100, the total score of the other 9 students is 700 – 100 = 600. The average score of the other 9 students is 600 / 9 = 66.67, which rounds to 68.
