Question

in a class test containing 12 marks 2 marks for every correct answer and -1 marks for every correct answer Ganesh grade 7 correct and incorrect answer what is a score

Answer 1

Answer:

Ganesh's score is 9 marks

Step-by-step explanation:

Given : no of questions in test = 12

            For correct answer = 2 marks

            For wrong answer = -1 mark

            Ganesh answered = 7 correct answer

            Ganesh's score = ?

Solution : Ganesh's wrong answer = total questions - correct answers

                                                         = 12- 7

                                                         = 5

               Ganesh score = No of correct answer x marks fo correct answer

                                          + No of wrong answer x marks for wrong answer

                                        = (7 x 2) + (5 x -1)

                                        = 14-5

                                         = 9 marks
