(i) Bharathi attempts all questions but only 9 answers are correct. What is her total score? (ii) One of her friends Hema attempts only 5 questions and all are correct. What will be her total score?​

Answer 1

Answer:

Mark's given for one correct answer=4

so, marks given for 9 correct answer are=4×9=36

marks given for one incorrect answer=-2

so,,, marks given for 6={15-9} incorrect answer

so,,,,,,,,,,,,6={15-9}={-2}×6=-12 therefore Hema's total socer is 36-12=24

Answer 2

Step-by-step explanation:

Marks given for one correct answer =4

So, marks given for 9 correct answers are

=4 X 9 = 36

Marks given for one incorrect answer

So, marks given for 6=(15-9) incorrect answers

= (-2) X 6 =-12

Therefore, Gurpreet's total score is
