Scoring System:
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
