Question

In a class test containing 15 questions 4 marks are given for every correct answer and (-1) marks are given for

every incorrect answer.

i) Gokul attempts all questions but only 6 of his answers are correct. What is his total score?

ii) Neena gets 12 of her answers correct. What will be her score?​

Answer 1

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 2

Answer:

I)6*4=24

9*-1=-9

24+(-9)=15

2)12*4=48

3*-1=-3

-3+24=21
