(新值-舊值)/舊值乘100%就是該手提電話的標價比來價高百分之幾?
x-0.6x
--------- x 100%
0.6x
5/3-1
= ------- x100%

設手提電話的標價為$y
手提電話的來價 = 手提電話的售價 = y * 60%
所以, 手提電話的標價比來價高:
( y - y * 60% )
--------------------- * 100%
y * 60%
( 1 - 0.6 )
=--------------- * 100%
0.6
0.4
=------- * 100%

let the selling price be Y
let the original price be Z
0.6Y=Z
The ratio of selling price to original price:
= Y / Z
=Y / 0.6Y
=1.66667
therefore, the selling price is higher than the original price by 67%

x = 標價
y = 來價相同
0.6 x = y
x = 1.67 y
標價比來價高 67%
y = 來價相同
0.6 x = y
x = 1.67 y
標價比來價高 67%
