Answer:
24
Step-by-step explanation:
Given:
Class test:
Total number of questions = 15
Every correct answer = 4 marks
Every incorrect answer = -2 marks
Gurpreet:
No. of questions attended = 15
Correct answer = 9
Total score = ?
Solution:
Marks for correct answer (Gurpreet) = 9 x 4
Marks for correct answer (Gurpreet) = 36 marks
No. of wrong answers (Gurpreet) = 15 - 9
No. of wrong answers (Gurpreet) = 6
Marks for wrong answers (Gurpreet) = 6 x -2
Marks for wrong answers (Gurpreet) = -12
Total Score = Marks for correct answer (Gurpreet) + Marks for incorrect answer (Gurpreet)
Total Score = 36 + (-12)
Total Score = 24
The Total score of Gurpreet = 24 Marks
Hope you found it HELPFUL!!
