Question

In a class test containing 10 questions, 5 marks are awarded for every correct answer and (–2) marks are awarded for every incorrect answer and 0 for questions not attempted.
Heena gets two correct and five incorrect answers out of seven questions she attempts. What is her score?

Answer 1

Hi there!
Here's the answer:

•°•°•°•°•°<><><<><>><><>°•°•°•°•°•

In the class test,
Total Questions = 10
For correct answer = +5 Marks
For incorrect answer = -2 Marks
For unattempted answer = 0 Marks

Score = (5 × No. of correct Answers) - (2 × No. of Incorrect Answers)

Given,
Heena attempted 7 answers
Remaining 3 unattempted
(Unattempted questions has nothing to do with total score)

Correctly answered = 2
Incorrectly answered = 5

Heena's Score = (5 × 2) - (2 ×5)

•°• Heena's score = 0

•°•°•°•°•°<><><<><>><><>°•°•°•°•°•

Hope it helps

Answer 2

✳️ Solution: for the given situation we know that the number of correct answers Heena attempted are 2

and incorrect answers are 5

total questions attempted = 7

to represent the situation we can convert the situation into a linear equation according to the marks and number of questions

$5(2)- 2(5)= 10-10 = 0$


by this way we had calculated that Heena scores a zero (0) in that test.
