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. Gurpreet attempts all questions but gets only 9 of her answers are correct. What is her total score?

Answer 1

Answer:

24

Step-by-step explanation:

Total no. of questions = 15

Corrrect = 9

Marks for each correct answer=4

Marks for correct=9 x 4=36

Wrong=15-9=6

Marks for each wrong answer=-2

Marks for wrong= -2 x 6= -12

Therefore total marks=36-12=24

Answer 2

Answer:

Marks given for 1 correct answer = 4

So, marks given for 9 correct answers = 4 × 9 = 36

Marks given for one incorrect answer = – 2

So, marks given for 6 incorrect answers = (–2) × 6 = –12

Therefore, Rishita’s Total score = Marks given for correct answers + Marks

given for incorrect answers

= 36 + ( –12)

= 24
