- Calculate total scores for the two groups:

- 30 students with an average score of 95: Total score = 30 * 95 = 2850.

- 10 students with an average score of 85: Total score = 10 * 85 = 850.

- Determine the combined total score:

Total score for class = 2850 + 850 = 3700.

- Find the average score for the whole class:

- Number of students = 40.

- Average score = Total score / Number of students = 3700 / 40 = 92.5.

- The correct option is:

- 92.5

- Your chosen option was option:2, which is 92.5.

- CORRECT ANSWER: 92.5
