Answer

To find out how much money Pooja has at the end of the day, we can break down the transactions step by step.

### Step-by-Step Solution:

1. **Initial Amount Received:**
Pooja receives Rs. 50 from her aunt.
\[ \text{Initial Amount} = 50 \]

2. **Amount Given to Seema:**
Pooja gives Rs. 40 to Seema.
\[ \text{Remaining Amount} = \text{Initial Amount} - \text{Amount Given to Seema} = 50 - 40 = 10 \]

3. **Amount Returned by Benu:**
Benu returns Rs. 30 that she owed to Pooja.
\[ \text{Total Amount Now} = \text{Remaining Amount} + \text{Amount Returned by Benu} = 10 + 30 = 40 \]

4. **Amount Spent on Buying a Pen:**
Pooja buys a pen for Rs. 10.
\[ \text{Final Amount} = \text{Total Amount Now} - \text{Amount Spent on Pen} = 40 - 10 = 30 \]

### Conclusion:
At the end of the day, Pooja has Rs. 30 left.
