Answer 1

Answer:

given,

one correct answer = 4 marks

one incorrect answer = - 2marks

(i) 10 correct answers = 10 x 40 = 40 marks

5 incorrect answers = 5 x (-2) = -10marks

total score = 40 + (-10) = 40 - 10 = 30 marks

(ii) 7 correct ansers = 7 x 4 = 28 marks

8 incorrect answers = 8 x (-2) = -16 marks

total score = 28 + (-16) = 28 - 16 = 12 marks
