Score Calculation for the Class Test
To determine the total score of the student in the class test, we will break down the scoring system based on the given information.
Total Questions
- The test consists of a total of 15 questions.
Correct Answers
- The student answered 7 questions correctly.
- For each correct answer, the student receives 4 marks.
Marks for Correct Answers
- Total marks from correct answers = Number of correct answers × Marks per correct answer
- Total marks from correct answers = 7 × 4 = 28 marks
Wrong Answers
- Since the student attempted all questions, the number of wrong answers = Total questions - Correct answers
- Number of wrong answers = 15 - 7 = 8
Marks for Wrong Answers
- For each wrong answer, the student loses 2 marks.
- Total marks lost from wrong answers = Number of wrong answers × Marks deducted per wrong answer
- Total marks lost = 8 × (-2) = -16 marks
Total Score Calculation
- The total score can be calculated by adding the marks from correct answers and subtracting the marks lost from wrong answers.
- Total Score = Marks from Correct Answers + Marks from Wrong Answers
- Total Score = 28 + (-16) = 28 - 16 = 12 marks
Final Score
- The student's final score for the test is 12 marks.
In conclusion, by analyzing the performance on the test, we see that the student scored 12 marks after accounting for both correct and incorrect responses.
