 In a test containing 20 questions, 3 marks are given for every correct answer and ( - 1) mark are given for every incorrect answer. Sona gets 10 correct answers and 6 incorrect answers. What is her total score?
​

Answer 1

Answer:

24

Step-by-step explanation:

Total questions = 20

3 marks for every correct answer

(-1) for every incorrect answer

Sona gets 10 correct and 6 incorrect

Therefore, {10*3}+{6*(-1)}

=30+(-6)

=24

The rest 4 answers were not attained so no marks

Answer 2

Answer:

total = 20

sona's correct answers = 10

sona's incorrect answers = ( -1 )

since, ( 10 x 3 ) + ( 6 x -1 )

now, = 30 + -6

so her total score equals 24
