Answer 1

A. -30 points

B. 60 points

Explanation:

20 points for correct answer and 10 points deducted for wrong answer

Each deduction is -10 while each correct answer gives + 20

4 questions correctly and 11 incorrectly

= 4(20) + 11(-10)

= 80-110 = -30 points

Second round

= 7(20) - 8(10)

= 140-80 = 60 points
