下表提供了有关考试中学生表现的有问题的数据。每个问题的分数也会列出。检查中没有负面或局部的标记。

班级在考试中获得的平均分数是多少
(A) 1.34
(乙) 1.74
(C) 3.02
(丁) 3.91答案： (C)
解释：

As you can see from each row that the total number of
students in the class are 44.

Now we have to find the total number of marks obtained
by the class.

Marks are given for correct answers only. 
No negative or partial marking.

For 1st question total marks obtained are : 2*21 = 42
For 2nd question total marks obtained are : 3*15 = 45
For 3rd question total marks obtained are : 2*23 = 46

hence total marks obtained by the class are = 42+45+46 = 133

Now, Average marks obtained = Total Marks/Total no of students
= 133/44
= 3.02
Hence C is the answer.
