Rohit purchased a notebook for Rs 23.75, a pencil for Rs 2.85 and a pen for Rs 15.90. He gave a 50-rupee note to the shopkeeper. What amount did he get back?

Answer

To solve the problem step by step, we will first calculate the total amount Rohit spent on the notebook, pencil, and pen, and then we will determine how much change he received after paying with a 50-rupee note.

### Step 1: Calculate the total amount spent
We need to add the prices of the notebook, pencil, and pen.

- Price of the notebook = Rs 23.75
- Price of the pencil = Rs 2.85
- Price of the pen = Rs 15.90

**Total amount spent = Price of notebook + Price of pencil + Price of pen**

Total amount spent = 23.75 + 2.85 + 15.90

### Step 2: Perform the addition
Now, let's add these amounts together.

1. Add Rs 23.75 and Rs 2.85:
- 23.75
- + 2.85
- __________
- = 26.60

2. Now, add Rs 15.90 to Rs 26.60:
- 26.60
- + 15.90
- __________
- = 42.50

So, the total amount spent by Rohit is Rs 42.50.

### Step 3: Calculate the change received
Next, we need to find out how much change Rohit received after giving the shopkeeper a 50-rupee note.

**Change = Amount given - Total amount spent**

Change = 50.00 - 42.50

### Step 4: Perform the subtraction
Now, let's subtract the total amount spent from the amount given.

- 50.00
- - 42.50
- __________
- = 7.50

So, the amount Rohit got back is Rs 7.50.

### Final Answer
Rohit received Rs 7.50 as change.
