12% per month? That's an incredibly high interest rate.

{{{F=P(1+i)^n}}}

I'm assuming interest is compounded monthly, {{{N=12*5=60}}}, {{{i=0.12}}}
{{{150000=P(1+0.12)^60}}}
{{{150000=P(897.597)}}}
{{{P=167.11}}}

In case interest is compounded annually, then {{{N=5}}}, {{{i=0.12*12=1.44}}}
{{{150000=P(1+1.44)^5}}}
{{{150000=P(86.487)}}}
{{{P=1734.37}}}
