Question

In a class test containing 20 questions, 3 marks are given for every correct answer and (-1) marks are given for every incorrect answer. Gurpreet attempts all questions but only 12 of her answers are correct and 8 are incorrect. The total score of Gurpreet is

Answer 1

Answer:

28 marks

Step-by-step explanation:

No. of questions = 20

Marks given for each correct answer = 3

Marks given for each wrong answer = -1

Gurpreet gives-

Correct = 12 answers

Incorrect = 8 answers

We know that:

Marks given for each correct answer = 3

Marks given for each wrong answer = -1

So,

Marks given for correct answers = No. of correct answers * marks awarded for each correct answer.

That is ,  12 * 3 = 36 marks

Marks given for incorrect answers = No. of incorrect answers * marks awarded for each incorrect answer

That is , 8 * -1 = -8

From this we can form an equation :

Gurpreet's total marks = 36 + ( -8 )

                                     = 36 - 8

                                     =28 marks in total

Therefore, Gurpreet's total marks are 28 marks.
