Answer:
72 points
Explanation:
To find the final score, add the score of correct answers with score of incorrect answers.
Score of 1 incorrect answer = -2
Score of 6 incorrect answers = 6 * (-2)
= -12
Total questions = 20
number of questions he answered correctly = Total questions - incorrect answers
= 20 - 6
= 14
Score for 1 correct answer = 6 points
Score for 12 correct answers = 14 * 6
= 84 points
Final score = Score for correct answers + score for incorrect answers
= 84 + (-12)
= 72 points
