Answer:

Number of questions = 15

Mark for correct answers = 4

Mark for incorrect answer = -2

(i) Correct answers = 9

Marks = 9x4 = 36 marks

Incorrect answers = 6

Marks = 6x-2 = -12 marks

Total marks = 36-12

= 24 marks

(ii) Correct answers = 5

Marks = 5x4 = 20 marks

Incorrect answers = 10

Marks = 10x-2 = -20 marks

Total marks = 20-20

= 0 marks
