#2.44%# loss

An item selling for #48# at a #25%# gain means that the cost price #(x)#was less.

#x/100 = 48/125" "(larr"money")/(larr"percent")#

#x = (48xx100)/125 = $38.40#

An item selling for #48# at a #20%# loss means that the cost price #(x)#was more.

#x/100 = 48/80" "(larr"money")/(larr"percent")#

#x = (48xx100)/80 = $60#

Total cost price = #$38.40 +$60 = #98.40#

Total selling price =# $48+$48 = $96#

Total loss = #$98.40-$96 = $2.40#

#2.40/98.40 xx 100%

#=2.44%# loss
