Answer 1

Answer:

Thus, Candidate Final Score will be 51.25.

Step-by-step explanation:

Given,

Total marks in an examination were 100.

A Candidate attempt 70 questions out of which 55 are correct.

we need to find the Candidate final score.

Sol: Questions Attempted by the Candidate = 70

                                                           Correct = 55

                                  ∴                   Incorrect = 70 - 55 = 15

        Marks on correct answers = $1*55=55$

        Negative marking of 1 incorrect answer = $\frac{-1}{4}$

     ∴ Negative marking of 15 incorrect answers =$\frac{-1}{4} *15=-3.75$

     Therefore, Candidate Final Score will be

                                   = Correct answer marks + Incorrect answer marks

                                   = 55 + (-3.75)

                                   = 51.25

     Thus, Candidate Final Score will be 51.25.
