Ans. i) The total correct answers given by Sona = 10
However, marks obtained by her = 20
Given, 1 correct answer fetches 3 marks:
So, Marks deducted for the incorrect answer
= {20 − (10 × 3)}
= {20−30}
= −10
Also it is given that: −1 mark is awarded for every incorrect answer.
Therefore, the number of total incorrect answers = (−1)/(-10) = 10
= {20 − (10 × 3)}
= {20−30}
= −10
Also it is given that: −1 mark is awarded for every incorrect answer.
Therefore, the number of total incorrect answers = (−1)/(-10) = 10
(ii) Total questions answered correctly = 10
Now, we also know that:
Now, we also know that:
Total incorrect answers = 10
Hence, total number of questions asked in the test = (10+10) = 20
