Having 29 correct answers is not possible because this means that there will be 12 incorrect answers and the total number of items will be 41 which is already over 40 without accounting for the items with no answer.
Having 32 correct answers is not possible because there will be no items with incorrect and no answer but it is given that Lina had incorrect answers, and no answers.
Answer: 30 correct, 8 incorrect, and 2 no answer; or 31 correct, 4 incorrect, and 5 no answer
