thats a jee question...usually found in materials of various institutes...

let it take x seconds to spend avo. no. of rupees

so x = avogad. no. /(10 lakh or 10^6)

= 6.022×10^17 sec.

1 day = 60×60×24 seconds

=> it will take 6.022×10^17 / 60×60×24 days...

now by dividing this with 365days or 1year....we'll get the no. of years required to spend avogadro number of rupees
