Given total number of questions = 20.
Given seven points awarded for each correct answer. So, 13 * 7 = 91.
Given that 2 points deducted for each wrong answer. So, 2 * 2 = 4.
= > 91 - 4
= > 87 scored by him
Now,
Total Questions = 13 + 2 = 15.
Questions he didn't answered = 20 - 15 = 5.
Therefore, he had omitted 5 questions.
Therefore, the answer - Option (B)
Hope this helps!
