✔ 最佳答案
Since John gets 9 questions correctly anwsered, his score will be (9 x 4)=36.At the same time, (24-18)=6 questions have no anwsers, therefore (6 x 2)=12
marks will be deducted.
As (18-9)=9 questions are not anwserd correctly, (9 x 3)=27 marks will be deducted.
Taking all factors into account, John's final score is (36-12-27)= (-3).
