Answer 2

Answer:

No.of marks for each question  = +5

No.of marks for incorrect question = -2

No.of marks Aaryav got = 30

If he got 10 answers right he would have earned 50 points . But he has 20 points less . We know that 10 × 2 = 20

So , we get to know that he has answered 10 questions incorrectly.
