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
