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

Answer:
Bharathi's Score:
24 marks out of 60 marks.
Explanation:
As Bharathi got 9 of the questions correct and 6 of the questions wrong, the equation for that will be, 9 x 4 + (-2 x 6) = 36 + (-12) = 24.
Her friend's score:
20 marks out of 60 marks.
Explanation:
As Bharathi's friend attempted only 5 questions and got the all correct, the equation for that will be, 5 x 4 + {0 x 10 = (0)} = 20 + 0 = 20.
Hope it helps!
