Answer»

Step-by-step EXPLANATION:

Total no. of questions= 15

For 1 CORRECT ANSWER marks awarded=4

For 1 incorrect answer marks awarded= -2

For Bharathi :

Total questions attempted=15

No. of correct answer= 9

Marks for correct answer=4×9=36

No. of incorrect answer=15-9=6

Marks for incorrect answer=(-2)×6= -12

So, total score= 36+(-12)= 36-12= 24

For Hema

Total no. of questions attempted= 5

No. of correct answers=5

Marks for correct answer=5×4= 20

So, total score= 20

Thus, the score of Bharathi is 24 & that of Hema is 20.
