ANSWER:
Given:
- Marks awarded for correct answer = +5
- Marks awarded for incorrect answer = -2
- Marks warded for unattempted question = 0
To Find:
- Marks scored by Reshma if she gets 6 correct answers and 4 incorrect answers.
- Marks scored by Heena if she gets 2 correct answers and 5 incorrect answers
Solution:
1) Marks scored by Reshma
We are given that,
⇒ Marks awarded for correct answer = +5
So,
⇒ Marks awarded for 6 correct answers = +5 × 6
⇒ Marks awarded for 6 correct answers = +30
And,
⇒ Marks awarded for incorrect answer = -2
So,
⇒ Marks awarded for 4 incorrect answers = -2 × 4
⇒ Marks awarded for 4 incorrect answers = -8
Hence,
⇒ Total marks = +30 + (-8)
⇒ Total marks = +22
Hence, total marks scored by Reshma is 22.
2) Marks scored by Heena
We are given that,
⇒ Marks awarded for correct answer = +5
So,
⇒ Marks awarded for 2 correct answers = +5 × 2
⇒ Marks awarded for 2 correct answers = +10
And,
⇒ Marks awarded for incorrect answer = -2
So,
⇒ Marks awarded for 5 incorrect answers = -2 × 5
⇒ Marks awarded for 5 incorrect answers = -10
Hence,
⇒ Total marks = +10 + (-1)
⇒ Total marks = 0
Hence, total marks scored by Heena is 0.
