Question 600014
Let {{{ x }}} = amount needed to start business
Makori contributes {{{ x/4 }}}
----------------------
The remainder is {{{ (3x)/4 }}}
Ondiek contributes {{{ (2/5)*((3x)/4) }}}
 {{{ (2/5)*((3x)/4) = (3/10)*x }}}
----------------------
Mosomi contributes {{{ (3/2)*(x/4) }}}
{{{ (3/2)*(x/4) = (3x)/8 }}}
----------------------
The remainder is
{{{ x - ( x/4 + (3x)/10 + (3x)/8 ) }}}
{{{ x - ( x/4 + (3x)/10 + (3x)/8 ) = (3x)/8 - 60000 }}}
{{{ x - x/4 - (3x)/10 - (3x)/8  = (3x)/8 - 60000 }}}
{{{ x - x/4 - (3x)/10 - (3x)/4  = - 60000 }}}
{{{ x*(  1 - 1/4 - 3/10 - 3/4) = -60000 }}}
{{{ x*( 40/40 - 10/40 - 12/40 - 30/40 ) = -60000 }}}
{{{ (x/40)*( 40 - 10 - 12 - 30 ) = -60000 }}}
{{{ ( x/40 )*(-12 ) = -60000 }}}
{{{ (-3/10)*x = - 60000 }}}
{{{ x = (10/3)*60000 }}}
{{{ x = 200000 }}}
The total amount required is 200,000
