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
