Answer 2

Answer:

Answer:

Rohit = 8 marks

Seema = 15 marks

Ritu = 0 marks

Step-by-step explanation:

Given :

Total questions = 10

Marks for correct answer = 5 marks

Marks for incorrect answers = (–2) marks

Marks for not attempting = 0 marks

Solution :

i) Rohit gets four correct and six incorrect answers. What is his score?

Correct = 4

Incorrect = 6

⇒ 5(4) + (–2) × (6)

⇒ 20 + (–12)

⇒ 8

Rohit scored = 8 marks

$$\rule{300}{1.5}$$

ii) Seema gets 5 correct and 5 incorrect answers. What is her score?

Correct = 5

Incorrect = 4

⇒ 5(5) + (–2) × (5)

⇒ 25 + (–10)

⇒ 15

Seema scored = 15 marks

$$\rule{300}{1.5}$$

iii) Ritu attempted 7 questions and gets only 2 correct answers. What is her score?

Correct = 2

Incorrect = 5

⇒ 5(2) + (–2) × 5

⇒ 10 + (–10)

⇒ 0

Ritu scored = 0 marks
