In a class of 60 pupils, `15%` remained absent on a rainy day. How many pupils were present in the class on that day ?

Answer

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the number of pupils absent
We know that 15% of the pupils were absent. To find out how many pupils that is, we need to calculate 15% of 60.

\[ \text{Number of absent pupils} = \frac{15}{100} \times 60 \]

### Step 2: Simplify the calculation
We can simplify the calculation as follows:

\[ \frac{15}{100} \times 60 = \frac{15 \times 60}{100} = \frac{900}{100} = 9 \]

So, 9 pupils were absent.

### Step 3: Calculate the number of pupils present
To find out how many pupils were present, we subtract the number of absent pupils from the total number of pupils.

\[ \text{Number of present pupils} = \text{Total pupils} - \text{Absent pupils} = 60 - 9 \]

### Step 4: Perform the subtraction
Now we perform the subtraction:

\[ 60 - 9 = 51 \]

Thus, the number of pupils present in the class on that day is 51.

### Final Answer
The number of pupils present in the class on that day is **51**.
