Answer:
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 O for questions not attempted. (ii) Reshma gets five correct answers and five incorrect answers, what is her score? Therefore, Reshma scored 15 marks.
Mohan get 4 correct answer = 4\times5\ =20\4×5 =20
He gets 6 incorrect answer = 6\times\left(-2\ \right)=\ -126×(−2 )= −12
Total score = 20-12\ =\ 8\20−12 = 8
Thus, mohan get 8 marks in the class test.
(ii) For 5 correct answer = 5\times5\ =\ 255×5 = 25
For 5 incorrect answer = 5\times\left(-2\right)=\ -105×(−2)= −10
Total score = 25-10\ =\ 1525−10 = 15
(iii) Heena get 2 correct answer = 5\times2=\ 105×2= 10
Heena get 5 incorrect = 5\times\left(-2\right)\ =\ -105×(−2) = −10
Total score = 10\ -10\ =\ 010 −10 = 0
Thus, total score of heena is zero.
