[機經] 幾題機經
5.People who earn more than 40000 for their salaries should submit 6% of
40000 and x% for the part exceeding 40000. If a people earn50000 and submit
2600, what is X?
Ans: 50000X=2600 X≒0.05
機經給的答案是0.05 但我自己算法跟解答不一樣 我算0.02
40000x0.06 + (50000-40000) A = 2600 , A = 0.02
因為爬文也沒看到有人討論這題,所以覺得很困惑...
19.一家公司把利潤從成本的10%提到15%，售價提到了$92，成本不變，問原價
假設成本為X 則 1.15X=92 X=80 原價為 80*1.1=88
答案88
我真的看不懂這題的列式，請高手幫忙說明一下~~
72.一個集合｛2,4,8,10,x}，x=?
1) 算朮平均數和中位數相等
2）x不等於16

我選A
麻煩了!! 先謝過了~~
