Answer 1

Answer:Mill attempts 9 correct answers. Marks obtainend by her for corrcet answers are 9*4=+36

in all 15 questions were there. It means incorrect answers attempted by her

were 15-9=6. Marks given for incorrect answers are 6*(-2)=-12

So marks obtained by Milli finally are +36-12=+24

John attempts only 5 correct answers . The marks alloted for correct answers are 5*4=+20

Incorrect answers attempted by him are 15-5=10

Marks giver for incorrect answers are 10*(-2)=-20

So total marks obtained by him are +20-20=0
