Question 992398
Let {{{ x }}} = his outlay
He sold at a loss, so
{{{ ( x - 72 ) / x = 1/7 }}}
{{{ 7*( x - 72 ) = x }}}
{{{ 7x - 504 = x }}}
{{{ 6x = 504 }}}
{{{ x = 84 }}}
-----------------
So I can use the same formula:
Let {{{ y }}} = % LOSS ( gain if it's negative )
If sold for {{{ 94.5 }}} rupees
{{{ ( 84 - 94.5 ) / 84 = y }}}
{{{ 84y = -10.5 }}}
{{{ y = -.125 }}}
{{{ -.125*100 = -12.5 }}}
There is a 12.5% gain
