A class of 60 students has an average score of 75. If 5 new students are added and the class average increases by 1, what is the average score of the 5 new students?
- 90
- 85
- 80
- 88
Correct answer: 88
Solution
Initial total score = 60 × 75 = 4500. New average = 76 for 65 students, so new total = 65 × 76 = 4940. Therefore, the 5 new students scored 4940 − 4500 = 440, giving an average of 88.
