Analysis of Mohini's Test Score:
Given Information:
- 3 marks for every correct answer
- -2 marks for every incorrect answer
- No marks for not attempting a question
- Mohini scored -5 marks in the test
- She got 7 answers correct
Calculating Number of Questions Attempted Correctly:
Let's assume Mohini attempted x questions correctly. Since she got 7 answers correct, her total score from correct answers would be 3 * 7 = 21.
Now, let's calculate her score from incorrect answers. Since she scored -5 in total, her score from incorrect answers would be -5 - 21 = -26.
Let y be the number of incorrect answers. Since each incorrect answer results in -2 marks, we can write the equation: -2y = -26 which gives us y = 13.
Therefore, Mohini attempted a total of 7 + 13 = 20 questions in the test correctly.
Explanation:
Mohini scored -5 marks in the test because the negative marks from the incorrect answers outweighed the positive marks from the correct answers. It is essential to be cautious while attempting questions in such tests to avoid losing marks for incorrect answers. By calculating the number of questions attempted correctly, we can understand Mohini's performance in the test and improve her strategy for future assessments.
