Marks: Find Maximum Examination Marks
Let the maximum marks for the examination be denoted by M.
Girish scored 572 marks.
This score was 30 marks less than 28% of the maximum marks.
This means that 28% of the maximum marks is equal to Girish's score plus the deficit:
$ 0.28 \times M = 572 + 30 $
$ 0.28 \times M = 602 $
To find the maximum marks M, we rearrange the equation:
$ M = \frac{602}{0.28} $
$ M = \frac{60200}{28} $
$ M = 2150 $
So, the maximum marks for the examination were 2150.
Percentage: Calculate Friend's Score Percentage
Girish's friend scored 473 marks.
The maximum marks are 2150.
To find the percentage of marks scored by the friend, we use the formula:
$ \text{Percentage} = \left( \frac{\text{Score Obtained}}{\text{Maximum Marks}} \right) \times 100 $
Substituting the values:
$ \text{Friend's Percentage} = \left( \frac{473}{2150} \right) \times 100 $
$ \text{Friend's Percentage} = \frac{47300}{2150} $
$ \text{Friend's Percentage} = \frac{4730}{215} $
$ \text{Friend's Percentage} = 22\% $
Therefore, the friend scored 22% of the maximum marks.
