In what system do you get .5 marks for a wrong answer?
Did you mean .5 marks are deducted for a wrong answer?
then what is 2(42) - 35(.5) ??
This question makes no sense.
If there are a total of 100 marks, and each correct answer is worth 2 marks, then there could only be a maximum of 50 questions.
How could the person answer 77 of them?
