Understanding the Problem: Calculating Percentage of Marks
The question asks us to find the percentage of marks scored by a specific student, Ravi, in a particular subject, Mathematics. We are given a table containing the marks obtained by five students (Ravi, Deepak, Sarita, Kamal, Divya) in five subjects (Hindi, English, Physics, Chemistry, Mathematics). The maximum marks for each subject is 150.
Data Extraction from Table
First, we need to locate the relevant information from the provided table:
- Student Name: Ravi
- Subject: Mathematics
- Marks Scored by Ravi in Mathematics: 141
- Maximum Marks Possible: 150
Table of Student Marks
| Subject/Student | Hindi | English | Physics | Chemistry | Mathematics |
|---|---|---|---|---|---|
| Ravi | 135 | 140 | 132 | 121 | 141 |
| Deepak | 120 | 135 | 139 | 112 | 136 |
| Sarita | 110 | 126 | 120 | 97 | 130 |
| Kamal | 130 | 125 | 98 | 102 | 120 |
| Divya | 136 | 130 | 101 | 100 | 115 |
Calculating Percentage of Marks
To calculate the percentage of marks, we use the formula:
$$ \text{Percentage} = \left( \frac{\text{Marks Scored}}{\text{Maximum Marks}} \right) \times 100 $$
Let's plug in the values for Ravi in Mathematics:
- Marks Scored = 141
- Maximum Marks = 150
Now, apply the formula:
$$ \text{Percentage for Ravi in Mathematics} = \left( \frac{141}{150} \right) \times 100 $$
Step-by-step Calculation:
- Divide the marks scored by the maximum marks: $$ \frac{141}{150} = 0.94 $$
- Multiply the result by 100 to convert it into a percentage: $$ 0.94 \times 100 = 94 $$
So, Ravi scored 94% in Mathematics.
Conclusion
The percentage of marks scored by Ravi in Mathematics is 94.
