Answer 2

Answer:

marks Nalini scored= (-7)

marks given for every correct answer= 3

marks provided for every incorrect answer= (-2)

marks provided for not attempting a question= 0

number of questions answered correctly= 9

number of questions answered incorrectly=?

to find the number of questions answered incorrectly we should substract 9 by (-2) till we get (-7)

like this

3+ 3= 6

6+ 3= 9

9 - 2= 7

7 - 2= 5

5 - 2= 3

3 - 2= 1

1 - 2= -1

now when we substract a negative number with a negative number we should add the numbers and put the minus sign

-1 - 2= -3

-3 - 2= -5

-5 - 2= -7

Nalini answered 11 questions and out of that she got 8 questions incorrect
