Answer 1

Answer:

24

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

=-2

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

= (-2) X 6 =-12

Therefore, Gurpreet's total score is

= 36 - 12 = 24
