Options

A. Class X has more percentage of students getting first class
B. Class Y has more percentage of students getting first class
C. Both classes have equal percentage of students getting first class
D. None of the above

Answer

To determine in which class the percentage of students passing in first class is higher, we will calculate the percentage for both classes step by step.

### Step 1: Calculate the percentage of students passing in Class X
- **Given**:
- Total students in Class X = 30
- Students passing in first class = 24

- **Formula**:
\[ \text{Percentage} = \left(\frac{\text{Number of students passing}}{\text{Total number of students}}\right) \times 100 \]

- **Calculation**:
\[ \text{Percentage in Class X} = \left(\frac{24}{30}\right) \times 100 \]
\[ = 0.8 \times 100 = 80\% \]

### Step 2: Calculate the percentage of students passing in Class Y
- **Given**:
- Total students in Class Y = 35
- Students passing in first class = 28

- **Formula**:
\[ \text{Percentage} = \left(\frac{\text{Number of students passing}}{\text{Total number of students}}\right) \times 100 \]

- **Calculation**:
\[ \text{Percentage in Class Y} = \left(\frac{28}{35}\right) \times 100 \]
\[ = 0.8 \times 100 = 80\% \]

### Step 3: Compare the percentages
- Percentage in Class X = 80%
- Percentage in Class Y = 80%

### Conclusion
Since both Class X and Class Y have the same percentage of students passing in first class, the answer is that both classes have equal percentages of students passing in first class.

### Final Answer
Both classes have equal percentage of students passing in first class.
