In a competitive exam, s marks. Ansect answer. (-2) marks are inonect ...
Given Data:
- Correct answer marks: +1
- Incorrect answer marks: -2
- Not attempted question marks: 0
- Total marks scored: 24
- Correct answers: 14

Calculating the Total Number of Questions:
Let the total number of questions be x.
Total marks = (Number of correct answers * Correct answer marks) + (Number of incorrect answers * Incorrect answer marks)
24 = (14 * 1) + (x - 14) * (-2)
24 = 14 - 2x + 28
2x = 18
x = 18/2
x = 9
So, the total number of questions in the exam is 9.

Calculating the Number of Incorrect Answers:
Let the number of incorrect answers be y.
Total marks = (Number of correct answers * Correct answer marks) + (Number of incorrect answers * Incorrect answer marks)
24 = (14 * 1) + (y * -2)
24 = 14 - 2y
2y = 14 - 24
2y = 10
y = 10/2
y = 5
Therefore, the candidate has attempted 5 questions incorrectly out of the total 9 questions.
