I) The total correct answer given by Sona was 10 but she obtained 20 marks.

1 correct answer of 3 marks then

Marks cut for the incorrect answer

=20 - 10 × 3 = 20 - 30 = -10

From question, -1 mark is given for every incorrect answer.

Hence, total incorrect answers

 =  \frac{ - 10}{ - 1}  = 10

2) Total correct answer given =10

Ans from part(I) we know that,

Total incorrect answer given =10

Therefore, the total question asked in the test (examination)

 = 10 + 10 = 20

 \\  \\ your \: required \: answer

please mark as brainliest please
