Study the given graph and answer the question that follows. The graph above depicts the marks of Devi in different subjects. What is her percentage of marks in Punjabi?
85%
90%
95%
80%
80%
Since the maximum marks are 50, you can simply multiply the obtained marks by 2 to get the percentage because 50 is half of 100.
Marks obtained by Devi in Punjabi = 45, Maximum marks per subject = 50.
Percentage=(Maximum┬аMarksMarks┬аObtainedтАЛ)├Ч100
Since the maximum marks are 50, you can simply multiply the obtained marks by 2 to get the percentage because 50 is half of 100.
Students often mistakenly divide the marks by the total sum of all subjects (145) instead of the per-subject maximum (50).
Identify Values
From the graph, identify the marks obtained by Devi in Punjabi, which is 45. The y-axis label indicates the marks are out of 50.
Marks=45,Total=50
Apply Percentage Formula
To find the percentage, divide the marks obtained by the maximum possible marks and multiply by 100.
Percentage=5045тАЛ├Ч100
Calculate Result
Simplify the fraction by dividing 100 by 50 to get 2, then multiply 45 by 2.
45├Ч2=90%
D is correct because Devi obtained 45 marks out of 50, which equates to 90%.
