Correct option is A

Solution:

Total number of students who appeared in the XYZ exam in the year 2012 = (500 + 300 + 200 + 100)

                                                                                                                           = 1100

Average number of students who appeared in the XYZ exam in the year 2012 = (1100/4)

                                                                                                                            =275
