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

Explanation

Total money to be spent `= 6.022 xx 10^(23)` rupees
Time taken to speed 10 lak `(10^(6))` rupees = 1s
Time taken to spend 1 rupee `= (1s)/(10^(6))`
`:.` Time taken to spend `6.022 xx 10^(23)` rupees `= (6.022xx10^(23))/(10^(6))s=6.022xx10^(17)s`
Time is seconds can be converted into time in years as follows :
`6.022 xx 10^(17)s=(6.022xx10^(17))/(60xx60xx24xx365)"yr"=1.91xx10^(10)` years.
