Question 942155
Let {{{ a }}} = cost price of fan sold at 10% gain
Let {{{ b }}} = cost price of fan sold at 10% loss
---------------------
{{{ a + .1a + b - .1b = 50000 }}}
{{{ 1.1a + .9b = 50000 }}}
------------------------
What if {{{ a = 25000 }}} and {{{ b = 25000 }}}
{{{ 1.1*25000 + .9*25000 = 50000 }}}
{{{ 27500 + 22500 = 50000 }}}
{{{ 50000 = 50000 }}}
Both fans cost $25,000
