Answer:
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

Answer:
i) 24
ii) 20
Step-by-step explanation:
i) number of correct answers = 9
marks for these answers = 9×4 = 36
number of incorrect answers = 6
marks for these answers = -2×6 = -12
Total score = 36 + -12 = 24
ii)number of correct answers = 5
marks for these answers = 5×4 = 20
number of incorrect answers = 0
marks for these answers = 0×-2 = 0
Total score = 20 + 0 = 20
Hope this helps you.
