A unit test paper contains 20 question.
3 marks for each correct
-1 marks for each incorrect
Anushka sets 8 correct and 12 incorrect answers
To Find:
Anushka Score
Solution:
Marks for 1 correct answer = 3
Marks for 8 correct answers = 8 * 3 = 24
Marks for 1 incorrect answer = -1
Marks for 12 incorrect answers = 12 * (-1) = -12
Total Marks = Marks for 8 correct answers + Marks for 12 incorrect answers
Total Marks = 24 + (-12)
Total Marks = 24 - 12
Total Marks = 12
