Answer:
Step-by-step explanation:
Total - 60 questions.....
So total marks = 60*2 = 120
Therefore if a question is attempted and is still wrong then the no. of marks lost = 2[2 marks per question]+1[For wrong answer] = 3
And he attempted all the questions......
Marks scored = 90
Therefore marks lost = 120-90 = 30
So no. of questions got wrong = 30/3 = 10
Answer = 10
