A person spends Rs. 10,000 per second.
In one year, he will spend = Rs. (10,000×3600×24×365) = Rs. 3.1536×10¹¹
1 mole rupees = Rs. 6.022×10²³ 

number\ of\ years=  \frac{total\ rupees}{rupees\ spent\ in\ one\ year} =\frac{6.022*10^{23}}{3.1536*10^{11}} =\boxed{1.91*10^{12}\ }

So it will take approximately 1.91×10¹² years to spend 1 mole rupees.
