Answer:
18 incorrect ..........
Step-by-step explanation:
Let the number of wrong answers be 'x'
number of correct answers = 12
marks earned for correct answers= 12*3 = 36
therefore, marks lost by wrong answers= 36-20 .= 16
marks lost by 1 wrong answer = 2
therefore, 16 marks are lost by 8 wrong questions...
