Answer:
i)Bharathi gets 24 marks
ii)Hema gets 20 marks
Step-by-step explanation:
i)Correct answers given by Bharathi=9
Therefore,number of incorrect answers=15-9
=6
Marks got for 9 correct answers=9x4
=36
Marks deducted for 6 incorrect answers=(-2)x6
=-12
Therefore,marks obtained by Bharathi=36+(-12)
=36-12
=24
ii)Marks obtained by Hema=5x4
=20
