Answer

To find out how much money Kunal received back after his purchases, we will follow these steps:

### Step 1: Identify the costs of the items purchased
- Cost of the notebook = ₹19.75
- Cost of the pencil = ₹3.85
- Cost of the pen = ₹8.35

### Step 2: Calculate the total cost of the items
We need to add the costs of all the items together.

\[ \text{Total Cost} = \text{Cost of Notebook} + \text{Cost of Pencil} + \text{Cost of Pen} \]

\[ \text{Total Cost} = 19.75 + 3.85 + 8.35 \]

### Step 3: Perform the addition
First, add the cost of the notebook and the pencil:

\[ 19.75 + 3.85 = 23.60 \]

Next, add the cost of the pen:

\[ 23.60 + 8.35 = 31.95 \]

So, the total cost of all items is ₹31.95.

### Step 4: Determine the amount given to the shopkeeper
Kunal gave the shopkeeper a ₹50 note.

### Step 5: Calculate the amount returned to Kunal
To find out how much money Kunal received back, we subtract the total cost from the amount he paid.

\[ \text{Amount Returned} = \text{Amount Paid} - \text{Total Cost} \]

\[ \text{Amount Returned} = 50.00 - 31.95 \]

### Step 6: Perform the subtraction
Now, let's subtract:

\[ 50.00 - 31.95 = 18.05 \]

### Conclusion
Kunal received ₹18.05 back from the shopkeeper.
