※ 引述《isss (Hua)》之銘言:
: Denoma, a major consumer-electronics maker, had a sizable decline in sales
: revenue for its most recent fiscal year. This result appears surprising,
: because electronics retailers report that although their overall sales were
: considerably lower than in the previous year, their sales revenue from
: Denoma models actually grew, largely thanks to some innovative and popular
: models that Denoma introduced.
: Which of the following, if true, does most to explain the apparently
: surprising result?
: A. Because of the need to educate the public about its new models’
: capabilities, Denoma’s advertising spending was higher than normal
: over the period.
以下提供幾個GMAT商業用語的簡單定義
profit = revenue - cost (spending)
revenue = unit price x quantity
cost = unit cost x quantity
而price則被demand與supply共同決定
: 想請教一下A選項為何是錯誤的?
: 若advertising spending 上升 也會導致revenue 相對減少
spending不算在revenue內,因此是無關選項。
從這邊延伸出去,補充一個GMAT邏輯的大考點--動態平衡
只要講到跟錢有關的東西,幾乎都是在premise說收入/支出 增加/減少
最後說利潤一定會增加/減少
這時候我們只要去想另外一邊是否有變動,便可找出相關答案
以下舉幾個過去整理機經所遇到的動態平衡題:
1. 填空-酪農業(2015-04機經)
儘管牛奶加工商跟養奶牛的酪農收購原奶(unprocessed milk)的價格上升了,
但酪農卻沒有賺取更多的利潤,因為_______。
填空 Ans:
乳牛吃的草料價格上升了。
2. 假設-房價上漲(2015-04機經)
某地過去幾年的房價不斷上漲,且人口也不斷上升。
專家預測該地在未來幾年人口會不斷上升,因此房價應該也會不斷上漲。
假設 Ans:
房子的 supply 不會跟 demand 一起上升。
3.削弱-貿易逆差(2015-05機經)
某國在某段時間的貿易逆差減少了,這代表該國的鼓勵出口政策有收到成效。
削弱 Ans:
該段時間該國的進口大量減少。
