Answer 1

Answer:

In a class test containing 10 questions, 5 marks are awarded for every correct answer and (−2) for each wrong and 0 for not attempted questions. We will just forget unattempted questions as it will give her 0 marks

So let us say for any student who gave x right questions and y wrong questions then total marks is given as 5x+(−2)y i.e

5x−2y total marks.

1) Mohan gets 4 correct and 6 incorrect so total score 5×4−2×6 i.e 8marks

2)Reshma gets 5 correct anf 5 incorrect do total marks scored is equal to

5×5−2×5 i.e 15marks

3)Heena gets 2 correct and 5 incorrect. She attempts only 7 questions so for the remaining 3 questions she will score zero marks.

So total marks scored by Heena is 5×2−5×2+0 i.e 0marks

Answer 2

Step-by-step explanation:

ANSWER

i) Tama gets 5 correct and 5 incorrect answers

To find his score

Since for every correct answer '3 marks are awarded '

For every incorrect answer '(−1) marks are awarded '

Total Score =5×3+5×(−1)

=15−5

=10

ii) Yama gets 7 correct answer and 3 incorrect answers

To find his score

Since for every correct answer '3 marks are awarded'

For Every Incorrect Answer ' (-1) marks are awarded '

Total score =7×3+3×(−1)

=21−3

=18

iii) Yaja gets 3 correct answer and 4 incorrect answers

To find his score

Since for every correct answer '3 marks are awarded '

For every incorrect answer '(−1) marks are awarded '

Total score =3×3+4×(−1)

=9−4

=5
