1. In a class of 22 students, 21 students get an average of 44 marks. If the remaining students get 66 marks, the average marks of the whole class is--
- A. 30
- B. 30
- C. 30
- D. 30
Answer: Option B
Explanation:
Total marks of the 21 students = 44 x 21 = 924
So, total marks of the whole class = 924 + 66 = 990
Average marks of the whole class = 990 / 22 = 45.
