Verified Answer
Directions: In an examination of 150 marks, all questions carry equal ...
Each question carries 3 marks.
Number of questions = 150/3 = 50.
5 unattempted questions fetch the student negative 5 marks
Assuming no question was wrong → Marks obtained by student = 45 × 3 – 5 = 130
For every wrongly answered question, the marks obtained will drop by 5.
So, marks obtained will always be a multiple of 5.

Explanation:

Given Information:
- Total marks in the examination: 150
- Marks awarded for correct answer: 3
- Marks deducted for wrong answer: 2
- Marks deducted for unanswered question: 1

Calculation:
1. For every correct answer, the student gets 3 marks.
2. For every wrong answer, the student loses 2 marks.
3. For every unanswered question, the student loses 1 mark.

Analysis:
- If the student answered 45 questions, the maximum marks they could have obtained is 45 * 3 = 135.
- However, for every wrong answer, 2 marks are deducted. So, the minimum marks the student could have obtained is 45 * 1 = 45.
- Therefore, the possible range of marks the student could have obtained is between 45 and 135.

Answer:
- Option 'A' with 92 marks cannot be obtained by the student because it falls outside the possible range of marks (45 to 135) based on the given conditions.
