Question

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 questions not attempted. Reshma gets five correct answers and five incorrect answers, what is her score?

Answer 1

5 correct out of 10 questions... so its 25 marks
5 incorrect out of 10 questions... so its -10
total score is 50 as if one correct answer is 5 marks... 10 correct answers will sum up to 50.
so... her score is 25 correct+ (-10) wrong... so it is 25+(-10) which equals to 15... her final score is 25+15 which equals to 40.

Answer 2

Correct answer = 5 marks

Wrong answer = - 2 marks

Marks awarded for 5 correct answer:

1 correct answer = 5 marks

5 correct answers = 5 x 5 = 25 marks

Marks deducted for wrong answer:

1 wrong answer = 2 marks

5 wrong answers = 2 x 5 = 10 marks

Find the final score:

Final score = 25 - 10 = 15 marks

Answer: She scored 15 marks
