Answer 1

Step-by-step explanation:

THERE ARE 5 SUBJECT =500MARK

FIRST CALCULATE THE ALL SUBJECT

=99×100/500=19.8%

=76×100/500=15.2%

=84×100/500=16.8%

=95×100/500=19%

=61×100/500=12.2%

AND ALL THE SUBJECT

99+84+76+61+95=415×100/500=83%

so she got 83%

Answer 2

The percentage of marks obtained by Ambika in the aggregate of all subjects=83%

Percentage of marks obtained by Ambika in the aggregate of all subjects if she  would secured 75% in english ad 80% in Hindi=86.6%

Step-by-step explanation:

Ambika got marks in Mathmematics=99%=$\frac{99}{100}\times 100=99$

Ambika got marks in Hindi=76%=$\frac{76}{100}\times 100=76$

Ambika got marks in English=61%=$\frac{61}{100}\times 100=61$

Ambika got marks in Science=84%=$\frac{84}{100}\times 100=84$

Ambika got marks in Social science=95%=$\frac{95}{100}\times 100=95$

Each subject carries marks=100

Total marks=5(100)=500

Total marks obtained by Ambika in all subjects=99+76+61+84+95=415

Percentage of marks obtained by Ambika in the aggregate of all subjects=$\frac{obtained\;marks}{total\;marks}\times 100=\frac{415}{500}\times 100=83$%

If Ambika got in Hindi=80%=$\frac{80}{100}\times 100=80$

If Ambika got in English=75%=$\frac{75\times 100}{100}=75$

Total marks obtained by Ambika in all subjects=99+80+75+84+95=433

Percentage of marks obtained by Ambika in the aggregate of all subjects=$\frac{433}{500}\times 100=86.6$%
