Answer:
1. 18 2. 14
Step-by-step explanation:
1. 9 correct = 9*6 = 54
18 wrong = 18*(-2)
so, add the marks to get her score
= 54+(-36)
=54-36 = 18 marks
therefore, she scored 18 marks
2. total question = 20,
36 marks = i question =6 maks
= 36/6
= he did 6 questions correct.
= he attemted 14 questions incorrectly
how he got icorrect = 20*6=120 total marks
so 20 question - 6 = 14 wrong questions
verify= 14 *6 =84 marks
120 - 84 = 36
we got the correct answer
plz mark brainliest.
