Answers
Answer:
(i) 24 marks
(ii) 0 marks
(iii) 42 marks
Step-by-step explanation:
Marks for correct = 4
Marks for wrong = (-2)
Marks for not attempted = 0
Total questions = 15
(i)
Questions Gurupreet attempted = 9 + 6 = 15
Questions Gurupreet got wrong = 6
Questions Gurupreet got correct = 9
Questions Gurupreet did not attempt = 0
Marks for wrong = 6 x (-2) = -12
Marks for correct = 9 x 4 = 36
Marks for not attempted = 0
Total marks = 36 + (-12) = 24 marks
(ii)
Questions Reema attempted = 10 + 5 = 15
Questions Reema got wrong = 10
Questions Reema got correct = 5
Questions Reema did not attempt = 0
Marks for wrong = 10 x (-2) = -20
Marks for correct = 5 x 4 = 20
Marks for not attempted = 0
Total marks = 20 + (-20) = 0 marks
(iii)
Questions Heena attempted = 12 + 3 = 15
Questions Heena got wrong = 3
Questions Heena got correct = 12
Questions Heena did not attempt = 0
Marks for wrong = 3 x (-2) = -6
Marks for correct = 12 x 4 = 48
Marks for not attempted = 0
Total marks = 48 + (-6) = 42 marks
