In a class test consisting 10 questions:

• 5 marks are awarded for each correct answer
• -2 marks are awarded for each incorrect answer
• 0 for each question not attempted

Performance of Ravi

4 correct and 6 incorrect answers

Performance of Renu

5 correct and 5 incorrect answers

To Find:

• Score of Ravi
• Score of Renu

Score of Candidate

= (Total no. of Correct Answers)×5+(Total no. of incorrect answers)×(-2)

Now,

Score of Ravi

= (4)×5+(6)×(-2)

= 20+(-12)

= 20-12

= 8

Score of Renu

= (5)×5+(5)×(-2)

= 25+(-10)

= 25-10

= 15

Hence, score of Ravi is 8 and score of Renu is 15.
