Answer 2

Answer:

Student A total marks = -4

Student B total marks = 20

Step-by-step explanation:

Total question = 25

Marks for correct answers = 4

Marks for incorrect answer = 2

Marks for not attempted question = 0

Student A:

Correct answers = 7

Marks for correct answer = 7 × 4 = 28

Incorrect answers = 18

Marks for incorrect answer = 18 × -2 = -36

Total marks = 28 - 36 = -4

Student B:

Correct answers = 10

Marks for correct answer = 10 × 4 = 40

Incorrect answers = 10

Marks for incorrect answer = 10 × -2 = -20

Question not attempted = 5

Question not attempted marks = 5 × 0

Total marks = 40 - 20 + 0 = 20
