各位大侠：

我是刚入手GMAT的新手，所以做逻辑题很不得要领，总是找不到题中的逻辑关系。请各位有何良法不吝赐教。谢谢！！！

另有OG第15题请教，

15、The cost of producing radios in Country Q is ten percent less than the cost of producing radios in Country Y ，Even after transportation fees and tariff charges are added，it is still cheaper for a company to import radios from Country Q to Country Y than to produce radios in Country Y。

The statement above，if true ，best support which of the following assentions？

A、Labor costs in Country Q are ten percent below those in Country Y，

B，Importing radios from Country Q to Country Y will eliminate ten percent of the manufacturing jobs in Country Y，

C、The tarruff on a radio imported from Country Q to Country Y is less than ten percent of the cost of manufacturing the radio in Country Y。

D、The fee for transporting a radio from Country Q to Country Y is more than ten percent of the cost of manufacturing the radio in Country Q。

E、It takes ten percent less time to manufacture a radio in Country Q than it does in Country Y，

别无他法,惟有狂练.具体可见牛人心经.

og15. 可当做数学问题

cost of Y-cost of Q=1/10 cost of Y

transportation fees +  tariff charges +cost of Q< cost of Y = cost of Q + 1/10 cost of Y

transportation fees +  tariff charges<1/10 cost of Y

同样可当数学题推理的还有og 175题. 好象是二元一次方程.
