Answer 1

Answer:

a) 41

b) 18

Explanation:

a) as given 5 marks for correct answer and -2 for wrong answer so she had 11 correct answer so her score will be 11*5=55. But she also had 7 wrong answer so her marks will deduct 7*2=14 therefore her total marks will be

55-14=41.

b) Her friend attempted 12 question and had 6 right answer so her score will be 6*5=30 but she also hve 6 wrong answer so her marks will deduct 6*2=12

therefore her total is

30-12=18
