Answer:
Ria's total score = 28
Manish's total score = 0
Step-by-step explanation:
There are total 20 Questions.
(+3) for correct answer and (-1) for incorrect answer.
Ria:
Attempted Questions = 20
Correct answers = 12
Incorrect answers = 20 - 12 = 8
Total score = (12 × 3) + (-1 × 8) = 36 - 8 = 28
Ria's total score = 28
Manish:
Attempted Questions = 20
Correct answers = 5
Incorrect answers = 20 - 5 = 15
Total score = (5 × 3) + (-1 × 15) = 15 - 15 = 0
Manish's total score = 0
