Question

10. In a class test containing 20 questions, 4 marks are given for every correct answer and (-2) marks for every incorrect answers.
i) Guru attempted all questions, but got 9 correct answers and 3 incorrect answers. What is Guru’s score? ​

Answer 1

Answer:

number of correct answers = 9

marks = 9*4 = 36

number of Incorrect answers = 3

marks = 3*(-2) = (-6)

number of questions Unattempted = 20-(9+3)

                                                         = 20-12 = 8

total score of guru = 36+(-6)+0

                               = 36+(-6)

                              = 36-6

                             = 30

I JUST TRIED I AM SORRY IF IT IS INCORRECT

THANKS
