Question

In a class test containing 15 questions, 4 marks are given for every correct answer and (–2) marks are given for every incorrect answer.(i) Gurpreet attempts all questions but only 9 of her answers are correct.
What is her total score? (ii) One of her friends gets only 5 answers correct. What will be her score?​

Answer 1

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 2

Step-by-step explanation:

(i)

If gurpreet attempt all the question but she gets 9/15=9×4=36

and her incorrect answer= 6×(-2)=-12

total marks score by gurpreet = 36+(-12)

=36-12

=24

(ii) Same as first
