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

Answer 1

1 correct ans. -5 marks

so, 5correct ans. - 25 marks

1 incorrect ans. -2 marks deduct

so, 6 incorrect ans. -6×2 =12,,25-12 =13

rohit scored 13 marks

Answer 2

Answer:

Rohit gets 4 correct answer so

1 correct ans = 5 marks,

so for 4 correct answer it's 20 marks.

and Other hand per incorrect answer will deducted 2 marks So for 6 incorrect Ans it will deducted 12 marks.

1.Rohit Final Score is 20-12= 8

Seema got 5*5= 25 for correct answer

and deducted 5*2= 10 marks

2.So Her final Score 25-10=15

So assume Ritu Gets 7answer wrong Sor for wrong answer 7*2= 14 will be deducted.

and for 2 correct Answer her score 10

3.Final score 10-14= -4
