Answer 1

Answer:

68.33

Step-by-step explanation:

Total marks of a student in 5 subjects = 65 * 5

                                                                = 325

Marks obtained in 6th subject = 65 + 20

                                                   = 85

Total marks obtained in all 6 subjects = 325 + 85

                                                               = 410

Mean marks in all 6 subjects = 410 /6

                                                = 68.33
