A person spends ten thousand rupees per second. Number of years that will take to spend approximately one mole of rupees is

Explanation

To solve the problem of how many years it will take for a person to spend approximately one mole of rupees at a rate of 10,000 rupees per second, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the concept of a mole**:
One mole of any substance contains approximately \(6.022 \times 10^{23}\) entities (Avogadro's number). In this case, we are considering one mole of rupees, which means we are dealing with \(6.022 \times 10^{23}\) rupees.

2. **Calculate the total time in seconds to spend one mole of rupees**:
The person spends 10,000 rupees per second. To find out how many seconds it will take to spend \(6.022 \times 10^{23}\) rupees, we use the formula:
\[ \text{Total time (seconds)} = \frac{\text{Total rupees}}{\text{Rupees per second}} = \frac{6.022 \times 10^{23}}{10,000} \]
Calculating this gives:
\[ \text{Total time (seconds)} = 6.022 \times 10^{19} \text{ seconds} \]

3. **Convert seconds to minutes**:
There are 60 seconds in a minute, so we convert seconds to minutes:
\[ \text{Total time (minutes)} = \frac{6.022 \times 10^{19}}{60} \]

4. **Convert minutes to hours**:
There are 60 minutes in an hour, so we convert minutes to hours:
\[ \text{Total time (hours)} = \frac{6.022 \times 10^{19}}{60 \times 60} \]

5. **Convert hours to days**:
There are 24 hours in a day, so we convert hours to days:
\[ \text{Total time (days)} = \frac{6.022 \times 10^{19}}{60 \times 60 \times 24} \]

6. **Convert days to years**:
There are approximately 365 days in a year, so we convert days to years:
\[ \text{Total time (years)} = \frac{6.022 \times 10^{19}}{60 \times 60 \times 24 \times 365} \]

7. **Final Calculation**:
Performing the final calculation:
\[ \text{Total time (years)} \approx 1.9 \times 10^{12} \text{ years} \]

### Conclusion:
It will take approximately \(1.9 \times 10^{12}\) years for the person to spend one mole of rupees at the rate of 10,000 rupees per second.
