Answer 2

Given:

Marks obtained by girl in English are 60 out of 75

Marks obtained by girl in Mathematics are 60 out of 90

Marks obtained by girl in Science are 80 out 100

To find:

Score of girl in percentage

Solution:

Total score of girl in all subjects=60+60+80

Total score of girl in all subjects=200

Total marks of all subject=75+90+100=265

Now,

Percentage marks=$\frac{Obtained\;marks}{Total\;marks}\times 100$

Using the formula

Score percentage of girl in English=$\frac{60}{75}\times 100=80$%

Score percentage of girl in Mathematics=$\frac{60}{90}\times 100=66.67$%

Score percentage of girl in Science=$\frac{80}{100}\times 100=80$%

Score of girl in percentage=$\frac{200}{265}\times 100$

Score of girl in percentage=75%
