8. In a class test containing 10 questions, 5 marks are awarded for every correct answer and (-2) marks are awarded for every incorrect answer and 0 for each question not attempted.
(i) Ravi gets 4 correct and 6 incorrect answer. What is his score?
(ii) Reenu gets 5 correct and 5 incorrect answers. What is her score?
(iii) Heena gets 2 correct and 5 incorrect answers. What is her score?

Solution:-

From the question we have 5 marks for correct answer and (-2) marks for incorrect answer.

Now. We get,

(i) Ravi’s score,

4 correct answer = 4 × 5 = 20

6 incorrect answer = 6 × (-2) = -12

= 20+ (– 12)

= 20 – 12

= 8

(ii) Reenu’s score,

5 correct answer= 5×5 = 25

5 incorrect answer= 5× (-2) = -10

= 25 + (-10)

= 25 – 10

=15

(iii) Heena’s score,

2 correct answer = 2 × 5 = 10

5 incorrect answer = 5× (-2) = -10

3 not attempted = 0

= 10 + (-10) +0

= 10 -10

= 0
