Answer 2

Every correct answer = 2 marks

Every wrong answer = -2 marks

Question (1):

Team A scored 20 marks (Given)

Number of correct answer = 10 (Given)

Total marks from the correct answer = 10 x 2 = 20 marks

Therefore

⇒ Team A did not attempt any of the other 10 questions.

⇒ Team A did not get any question wrong

Question (2):

Team B scored -10 marks (Given)

Number of correct answer = 10 (Given)

Total marks from the correct answer = 10 x 2 = 20 marks

Difference in marks = -10 - 20 = -30

Number of wrong questions = -30 ÷ (-2) = 15

⇒ Team B answered 15 questions wrong
