(b) Nimish gets 6 correct and 12 incorrect answers. What is his score?​

Answer 1

Answer:

(a) Neeti gets 68 marks

(b)Nimish gets 0 marks

Step-by-step explanation:

(a) Neeti attempted (18+3)=21 questions.

   Total questions  were 25. So she did not attempt 4 questions. Since 0          marks are awarded for very question not attempted, she got 0 for these.

    She got 18 questions correct. 4 marks are awarded for every correct question. So, she got a total of 72 marks for the correct questions.

    However, she got 3 questions wrong. So, she got a total of (-6) for these questions. If you add the marks, you will see that she got 68 marks.

(b) Following the above steps, you will find yourself with the marks :

•      24 for correct answers
•      -24 for incorrect answers
•      0 for not attempted questions

    So, he gets a total of 0 marks.
