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?

0 points

Step-by-step explanation:

So first we see that she gets 2 questions correct,

2 * 5 = 10

Then we see that she gets 5 questions wrong,

5 * -2 = -10

Then we see that she doesn't attempt three questions,

3 * 0 = 0;

Now we add up the points,

10 - 10 + 0 = 0 points

Heena gets 2 correct and 5 incorrect. She attempts only 7 questions so for the remaining 3 questions she will score zero marks.

So total marks scored by Heena is 5×2−5×2+0  i.e 0marks
