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

Text Solution

Verified by Experts

10 lakh `= 10 xx 100000 = 10^(6)`
1 Avogadro's number of rupees `= 6.023 xx 10^(23)`
`10^(6) "rupees" implies 1 s`
`6.023 xx 10^(23) "rupees = (1 xx 6.023 xx 10^(23))/(10^(6)) s`
`= (6.023 xx 10^(23))/(10^(6) xx 60 xx 60 xx 24 xx 365)` years
`= 1.9099 xx 10^(10)` years
