here is ur answer
marks given for every correct answer=3
marks given for every incorrect answer=(-1)
maximum marks=20×3=60
no. of questions done correctly by jefri=12
marks he got for the correct answer =12×3=36
no. of questions done wrong by jefri=20-12=8
marks he got for the incorrect answer=8×(-1)=(-8)
total marks he obtained =36+(-8)
