In a class, 5% students are absent on a particular day. If the number of students present on that day is 38 , the total strength of the class is :

Options

A. 45
B. 50
C. 40
D. 33

Answer

To find the total strength of the class, we can follow these steps:

### Step 1: Understand the percentages
We know that 5% of the students are absent, which means that 95% of the students are present.

### Step 2: Set up the equation
Let the total strength of the class be represented as \( x \). Since 95% of the students are present, we can write the equation:
\[ 0.95x = 38 \]

### Step 3: Solve for \( x \)
To find \( x \), we need to isolate it in the equation. We can do this by dividing both sides of the equation by 0.95:
\[ x = \frac{38}{0.95} \]

### Step 4: Calculate \( x \)
Now, we perform the division:
\[ x = \frac{38}{0.95} = 40 \]

### Step 5: Conclusion
Thus, the total strength of the class is \( 40 \).

### Final Answer
The total strength of the class is **40**.
