Answer:
100 marks have been obtained in the hindi subject.
Step-by-step explanation:
First you have to find how many marks are obtained by one degree. So you have:
450marks/360°=1.25marks/degree
Then you have to find how many marks are obtained for each subject.
1.25marks/degree×80°= 100 marks
1.25×72= 90 marks
1.25×70= 87.5 marks
1.25×90= 112.5 marks
1.25×48= 60 marks
100+90+87.5+112.5+60=450 marks
