翻译：一个男人卖了两个饰品,每个120元.其中一个饰品,他赚了20%.但另一个饰品,他亏损了20%.请找出两个销售的整体利润或亏损.
loss of $10.（整体亏损：10元）
但是我不知道它的作法.
希望数学高手给我它的算法,感激不尽啊!

120*2-(120/1.2+120/0.8)=-10

赚的饰品成本：120/(1+20%)=100
亏的饰品成本：120/(1-20%)=150
总成本：100+150=250
亏250-（120+120）=10

算出两个商品的原价，一个是100，一个是150，就好了
120/(1+20%)=100;120/(1-20%)=150.

一个成本价x 赚了20% x(1+20%)=120 x=100
一个成本价y 亏损20% y(1-20%)=120 y=150
总成本 100+150=250
卖的价钱 120+120 =240
所以整体亏损250-240=10

120×2=240元 120÷（1+20%）= 100元 120÷（1-20%）=150元 240-（100+150）=-10元答：亏了10元。

赚了20%的原价为：120除以120/100=100
亏了20%的原价为：120除以80/100=150
利润：赚了100X20%=20
亏了150-120=30
结论：30-20=10 亏损10元
假设两件商品原价都为100%，卖120元赚了20%的，120元就为原价的120%，所以要除以120%。

赚了20%的原价为：120除以120/100=100
亏了20%的原价为：120除以80/100=150
利润：赚了100X20%=20
亏了150-120=30
结论：30-20=10 亏损10元
假设两件商品原价都为100%，卖120元赚了20%的，120元就为原价的120%，所以要除以120%。
卖120元亏了20%，120元就为原价的80%，所以要除以80%
