Answer 1

Step-by-step explanation:

total no. of questions = 10

marks awarded for correct answer = 5

marks awarded for wrong answer = (-2)

1) correct answer = 4

wrong answer = 6

So his score is = (4×4)+(6×-2)

= 16 - 12

= 4 marks

2) correct answer = 5

incorrect answer = 5

So his score is = (5×4)+(5×-2)

= 20-12

= 8 marks

3) correct answer = 2

incorrect answer = 5

So his score is = (2×4)+(5×-2)

= 8-10

= -2 marks
