As 9 questions are correct so = 36
all are attempted
so rest are wrong
so 6 questions are wrong
therefore -2×6 =-12
So36 -12= 24
her friend attempts 5 question and all are correct so score = 4×5 = 20
total score= 20+24= 44
all are attempted
so rest are wrong
so 6 questions are wrong
therefore -2×6 =-12
So36 -12= 24
her friend attempts 5 question and all are correct so score = 4×5 = 20
total score= 20+24= 44
