Question

An examination has 10 questions. Each correct answer gets 1 mark and for each wrong answer 2 al negative mark. If Kalisha done 5 questions right and 5 questions wrong, what would be her total marks?​

Answer 1

Answer:

5 right *1 mark= 5marks

5 wrong *2 negative mark= -10 marks

so total -5marks

Answer 2

Answer:

Kalisha got (-5) marks

Step-by-step explanation:

Given number of questions = 10

marks for correct answer = 1 mark

negative mark for wrong answer = -2

kalisha done 5 right answers

then marks that will she get =  5 × 1 marks = 5

kalisha did 5 wrong marks

then negative marks will she get= 5 × (-2) = -10

total marks she got = marks for right answer + negative marks

                                =  5 - 10 = -5 marks
