The average score of 10 students is 75. If one student scoring 60 is removed, what is the new average of the remaining 9 students?
A72
B73
C75
D76.67
Answer & Solution
Correct answer: D. 76.67
Total of 10 = 75 × 10 = 750. After removing the 60: new total = 690. New average = 690 / 9 ≈ 76.67. (Removing a below-average score raises the mean of the rest.)
