only 5 questions and all are correct. What will be her total score?​

Answer 1

Answer:

firstly bharathi

she attempts all questions means 15 question

and 9 questions are correct then 6 questions are incorrect and for every correct question 4 marks are allotted then 9*4=36,and for every incorrect question -3 marks are allotted then bharathi gains (9*4)+(6*-3)=36-18=18

secondly HEMA

HEMA attempts only 5 questions and all questions are correct no in correct question then HEMA get (5*4) +(0*-3)=20-0=20

bharathi =18 marks

HEMA =20 marks
