i) John's correct answer = 8

John's correct answer marks = 8 × 4 = 32

John's wrong answer = 2

John's wrong answer = 5

John's total mark = 32 - 5 = 27 marks

ii) Sam's correct answer = 4

Sam's correct answer marks = 4 × 4 = 16

Sam's wrong answer = 1

Sam's wrong answers mark = 3

Sam's total mark = 16 - 3 = 13 marks
