Answer 1

Step-by-step explanation:

marks awarded for correct answer is +4 marks

marks awarded for wrong answer is -2 marks

for not attempting any question is zero marks

so, ravi got 20 marks

he attempted 8 correct answers so from that he got 8×4=32 marks

so by attempting wrong answers he got 20 marks

so 32-20=12 marks

12÷2 = 6 incorrect answers he attempted.
