Study the given graph and answer the question that follows.

The graph shows the marks obtained by Riya and Rida in six subjects in the CBSE 12^th exam. The maximum marks in Maths, Physics and Chemistry are 140, and that in English, IP, Biology are 180

What is the percentage of marks obtained by Riya in Chemistry?

The correct answer is 92.86%.

From the given line graph, we can observe the marks obtained by Riya (represented by the blue line with diamond markers) and Rida in six subjects.

Looking specifically at Chemistry for Riya:

Marks obtained by Riya in Chemistry = 130

As given in the question, the maximum marks for Chemistry are 140.

To find the percentage of marks obtained by Riya in Chemistry, we use the percentage formula:

$\text{Percentage}=\left(\frac{\text{Marks Obtained}}{\text{Maximum Marks}}\right)\times 100$

Substituting the values into the formula:

$\text{Percentage}=\left(\frac{130}{140}\right)\times 100$

$\text{Percentage}=\frac{1300}{14}=\frac{650}{7}\approx 92.857\%$

Rounding to two decimal places, we get 92.86%.
