Marks for correct answer = 56
Marks for wrong answer = -20
Total answer = 56 + (-20)
= 56 - 20
= 36.
No.of correct answers = Marks for correct answer / 2
=> 56 / 2
= 28
No.of wrong answers = Marks for wrong answers / -1
=> -20 / -1
=> 20
Marks for wrong answer = -20
Total answer = 56 + (-20)
= 56 - 20
= 36.
No.of correct answers = Marks for correct answer / 2
=> 56 / 2
= 28
No.of wrong answers = Marks for wrong answers / -1
=> -20 / -1
=> 20
