Question

Q.6- (II) :-

In a competition, 3 marks are given for each correct answer, and (-2) marks are given for each incorrect answer, and no marks for not attempting any questions.

Nalini scores (-7) marks in this competition, though she has got 9 correct answers. How many questions has she attempted incorrectly?

Solution

Given:-

  • Correct answers give 3 marks.
  • Incorrect answers give -2 marks.
  • Not attempting gives 0 marks.

Let's find the sum of her marks.

It is given that she scored (-7) marks and got 9 correct answers. That means she was given 27 marks for correct answers.

Let the number of incorrect answers by her be x. For each of them, (-2) marks are given.

\implies 27-2x=-7

\implies -2x=-34

\implies x=17

She got 17 incorrect answers.
