Question

Shruti secured 60% marks in mathematics 55% in English and 60% in Hindi.if the maximum marks is in the subjects were 75,60 and 65 respectively find the aggregate percentage of marks.

Answer 1

Percent scored in Mathematics = 60%

=> Marks scored in Mathematics
= 60/100 × 75

= 45 marks


Percent in English = 55%

=> Marks in English = 55/100 × 60

=> 33 marks

Percentage in Hindi = 60%

Marks in hindi = 60/100 × 65

=> 39 marks

So aggregate percent

= (sum of obtained marks)/(sum of max marks) × 100

=> (45+33+49)/(75 + 60 + 65) × 100

=> 117/200 × 100

=> 117/2

= 58.5%

Hope it helps dear friend ☺️

Answer 2

since,

percentage of marks scored by Shruti in mathematics = 60%

Marks scored by Shruti in mathematics = $\tt{\frac{60}{100}}$ × (maximum marks in mathematics)

= $\tt{\frac{60}{100}}$ × $\textsf{75}$

= $\tt{45 marks}$

percentage of marks scored by Shruti in English = 55%

Marks scored by Shruti in English = $\tt{\frac{55}{100}}$ × (maximum marks in English)

= $\tt{\frac{55}{100}}$ × $\textsf{60}$

= $\textsf{33 marks}$

percentage of marks scored by Shruti in Hindi = 60%

Marks scored by Shruti in hindi = $\tt{\frac{55}{100}}$ × (maximum marks in hindi)

= $\tt{\frac{60}{100}}$ × $\textsf{65}$

= $\textsf{39 marks}$

Now,

Total Percentage of marks = $\tt{\frac{sum\: of\: marks}{sum\: of\: maximum\: marks}}$ × $\textsf{100}$

= $\tt{\frac{45 + 33 + 39}{75 + 60 + 65 }}$ × $\textsf{100}$

= $\tt{\frac{117}{200}}$ × $\textsf{100}$

$= 58.5\%$
