If your exam has 100 questions and you answered 53 questions correctly and 39 questions wrongly, and if there is a negative marking of 0.23 marks for each wrong answer, we can find your total marks by a simple calculation. For the correct answers, you get full marks, so 53 right answers give you 53 marks. For the wrong answers, marks will be deducted. So, 39 wrong answers multiplied by 0.23 means you lose 8.97 marks.Now, to find your final score, subtract the negative marks from the correct marks. That means 53 minus 8.97, which is equal to 44.03 marks. So, your total marks in the exam will be 44.03 out of 100. This method shows how negative marking affects your final score and helps you understand where your total marks come from.
