number of questions on class test = 15
number of marks given for correct answers=4
number of marks given for incorrect answers=-2
number of answers Garima got correct=9
total score of Garima=9x4=36
total score of garima after incorrect answer=So, marks given for 6=(15-9) incorrect answers = (-2) X 6 =-12
= 36 - 12 = 24
total score of amitha =5x4 = 20
total score of amitha after incorrect answer = 10x-2=-20
20-20=o
total marks for test=15x4=60
therefore,garima scored 24/60 and amitha scored 0/60.
