    Answer:

    good night dear

    i like to help you….

    Thanks for asking the question with me..

    Step-by-step explanation:

    Here, we are given positive marks every correct answer and negative marks for every incorrect answer i.e. for the correct answer =+5 and for every incorrect answer =−2 marks. So, the total marks for correct answer = marks for correct answer × number of correct answers.
