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
