a student scored 55% in the first exam and 70% in the second exam what should he score in the third exam so as to get 70% as an overall score​

Answer 1

Answer:

ANSWER

Percentage in science =75%

Total marks=80

⇒Marks obtained in science =75% of 80

=10075×80=60 marks

In mathematics=95%

Total marks=100

⇒ Marks obtained =95% of 100

=10095×100=95 marks

In English, marks=70%

Total=70marks

⇒ Marks obtained=70% of 70

=10070×70=49 marks

⇒ Total marks obtained=60+95+49

=204 marks

Maximum marks=80+100+70

=250 marks

⇒ Aggregate percentage=250204×100

=5408=81.6%.
