Answer 1

Percentage in science =75%

Total marks=80

⇒Marks obtained in science =75% of 80

=

100

75

×80=60 marks

In mathematics=95%

Total marks=100

⇒ Marks obtained =95% of 100

=

100

95

×100=95 marks

In English, marks=70%

Total=70marks

⇒ Marks obtained=70% of 70

=

100

70

×70=49 marks

⇒ Total marks obtained=60+95+49

=204 marks

Maximum marks=80+100+70

=250 marks

⇒ Aggregate percentage=

250

204

×100

=
