Answer 2

Given:

The rate at which money can be spent = 10 lakh rupees per second

To find:

How many years it would take to spend Avogadro's number of Rupees at the rate of 10 lakh rupees per second?

Solution:

We know that the value of Avogadro's number = 6.023×10²³

If we spend 10 lakh rupees per second, then the number of seconds that we will take to spend 6.023×10²³ will be:

= $\frac{6.023*10^{23} }{10^{6} }$

On solving, we get:

= $6.023*10^{17}$ seconds

Now, we will convert seconds into years:

$= \frac{6.023*10^{17} }{365*24*60*60}$

On simplifying, we get:

= $1.9099*10^{10} years$

Thus we can say that if we spend 10 lakh rupees per second, then the number of seconds that we will take to spend 6.023×10²³ will be $1.9099*10^{10} years$.

Thus, option 1 is correct.
