​

Answer 1

Answer:

Hello! Mate, here is you answer.

Gurpreet's total score will be 24.

Step by step answer:

Total number of questions = 15 questions

Marks for each correct answer = 4 marks

Marks given for every incorrect answer = {-2} marks

Number of questions attempted by Gurpreet = 16 question

Number of correct answers = 9 answers

so, for her nine correct answers she will get

9 × 4 = 36 marks.

Number of incorrect answers = 6 answers

so, for her 6 incorrect answers she will get

6×(-2) = (-12) marks

Now, add all her marks.

36 marks + (-12) = 24 marks.

So, Gurpreet's total score will be 24 marks.
