Question

In a class test of 15 questions, 4 marks are given for every correct answer, (–2) marks for every incorrect answer and 0 for questions not attempted. (i) Priya gets 7 correct and 4 incorrect answers. What is her score? (ii) Ram gets 11 correct and his total score is 40 marks. Calculate the number of incorrect answers given by him.

Answer 1

marks for right answers- 4

marks for wrong answers- (-2)

Priya got 7 correct so she got 28 marks, and 4 incorrect so (-8), so the total score is 20.

Ram got 11 correct so the score is 44, but his total score is 40 this means there are two incorrect answers and the score is (-4), so the total score is 40.

so the number of incorrect answers are 2.

Answer 2

Answer:

Priya's score: 20

wrong answers given by Ram: 2

Step-by-step explanation:

Priya's score:

7 correct answers: 7 x 4 = 28

4 wrong answers: -2 x 4 = -8

overall score: (sum of the two) 28 - 8 = 20

Ram's wrong questions:

11 correct answers: 11 x 4 = 44

number of incorrect answers= (correct answers - total marks) / (|marks for every incorrect answer|)

= (44 - 40) / 2

= 4/-2 = 2.

please mark as brainliest.
