Answer:
Given that test has been conducted containing 20 questions , 4 mark were given to the right answers and 2 marks were deducted to the wrong answer
According to the question
Alex attempt all the questions but 11 of them are right and 9 of the them are wrong
so first Alex attempted all questions
20×4= 80 marks
after the correction
9 of them are wrong so
as 2 marks were deducted to the wrong answers
2×9=18
the total mark is 80-18= 62 marks
Hence the required answer is 62 marks
hope it helps you ✌️✅✅✅
