In a certain year the United Nations' total expenditures were $1.6 billion. Of this amount, 67.8 percent was paid by the 6 highest-contributing countries, and the balance was paid by the remaining 153 countries. Was Country X among the 6 highest-contributing countries?

(1) 56 percent of the total expenditures was paid by the 4 highest-contributing countries, each of which paid more than Country X.

(2) Country X paid 4.8 percent of the total expenditures.

Ans:E

想請問有無大大知道這題解題的捷徑

總消費 1.6 billion, 其中六國是消費最高的，佔1.6 billion 67.8%, 剩下的趴數就是那153國的
問： X 這一個國家是不是就是這消費最高的6國的其中一國

(1) 只告訴我最高的 4 國總消費，有 56 % 。==> 可是題目說有6個國是消費最高的，只告訴我4國，還有兩國分別多少不知道，更不知道153國每一國的消費支出，無法判斷 X 國是不是就是屬於這六國的中其一國
(2) X 國佔了總消費支出的 4.8 %。 仍然無法判斷

(1)+(2) 雖然告訴我有四國的消費，有兩國未知，我不知道 4.8%是落在這最高的其中兩國，還是落在153國之中
答案就 E
