∵ 1 correct answer of 3 marks then
Marks for the correct answers given = 3 x 10 = 30
Marks cut for the incorrect answer = 20 - 30 = - 10
As, -1 mark is given for every incorrect answer.
Hence, total incorrect answer = −10−1 = 10
Total incorrect answer given = 10 taken from the first part of the question.
Therefore, the total question asked in the test (examination)
= 10 + 10 = 20
