Answer:

27

Explanation:

Mark obtained for each correct answers = +6

Total correct answers given = 7

Marks obtained for all correct answers = 6×7 = 42

Marks obtained for each incorrect answers = -5

Total incorrect answers given = 3

Marks obtained for all incorrect answers = 3×(-5) = -15

Total marks obtained = Marks scored for all correct answers - Marks scored for all incorrect answers = 42 - 15 = 27
