Scoring System:
Correct Answer : +5 marks
Incorrect Answer : -2 marks
Not attempted : 0 marks
(i) Mohan gives 4 correct and 6 incorrect answers.
∴ Mohan's Score = 4*(5) + 6*(-2)
= 20 - 12
= 8 marks
(ii)Reshma gives 5 correct and 5 incorrect answers.
∴ Reshma's score = 5*(5) + 5*(-2)
= 25 - 10
= 15 marks
(iii)Heena gives 2 correct and 5 incorrect answers.
∴ Heena's score = 2*(5) + 5*(-2)
= 10 - 10
= 0 marks
