Answer:
(i) 8
(ii) 15
(iii) 0
Step-by-step explanation:
(i) Mohan gets 4 correct and 6 incorrect answers
Mohan's score = 4 x 5 + 6 x -2
= 20 + -12
= 8 (answer)
Therefore, Mohan's score is 8.
(ii) Reshma gets 5 correct and 5 incorrect answer
Reshma's score = 5 x 5 + 5 x -2
= 25 + -10
= 15 (answer)
Therefore, Reshma's score is 15.
(iii) Heena gets 2 correct, 5 incorrect and 3 unanswered answers
Heena's score = 2 x 5 + 5 x -2 + 3 x 0
= 10 + -10 + 0
= 0
Therefore, Heena's score is 0.
