In a class test containing 10 questions, 4 marks are awarded for every correct answer and

(-2) marks are awarded for every incorrect answer and 0 for questions not attempted.

(i) Anil gets 6 correct answers and 4 incorrect answers. What is his score?

(ii) Sunil gets 5 correct answers and 5 incorrect answers. What is his score?

(iii) Rahul gets 1 correct answer and 3 incorrect answers out of 4 questions he attempted.​

Answer 1

$\tt 1) \: \: (6 \times 4) + ( - 2 \times 4) = 24 - 8 = 16 \: marks$

$\tt 2) \: (5 \times 4) + (5 \times - 2) = 20 - 10 = 10 \: marks$

$\tt 3) \: (1 \times 4) + (3 \times - 2) = 4 - 6 = - 2 \: marks$

Answer 2

Answer:

i) 16 marks

ii) 10 marks

iii) -2 marks

Step-by-step explanation:

i) 6 x 4 = 24

4 x (-2) = (-8)

24 + (-8) = 16

ii) 5 x 4 = 20

5 x (-2) = (-10)

20 + (-10) = 10

iii) 1 x 4 = 4

3 x (-2) = (-6)

4 + (-6) = (-2)

I hope this helped
