A lamp which normally sells for $180 was puchased by a consumer for $120. How much of a discount dad the consumer receive?
呢條點計？
係計%定得到幾多錢？
咩意思？

✔ 最佳答案
計discout即係計個減價比起原價的百分比%一般係以減價(即原價 - 售價)除以原本價錢 再乘以 100%
現原價是 $180
減價是 $60 ($180-$120)
所以 discount
= $60 / $180 x 100%
=1/3 x 100%
=33.33%
以上朋友都計得對, 但題目就是這樣解釋
記住, 減價=原價 - 最後售價
計discount時, 分母一定是原價

計%
180-120
----------- x100%
180
=33.333333333......%
180-120
----------- x100%
180
=33.333333333......%

180－120/180(100％)＝33.33％
2007-01-09 4:44 pm
120/180x100%=33.33% discount
2007-01-09 3:56 pm
180－120/180×100％＝33.33％

discount應該都係計percentage既
折扣麻~
(180-120)/180*100%
小弟愚見~

即係一盞燈原本的售價是$180
而家顧客以$120就買到了.
咁即係該顧客有幾多discount.
ans:大概33% off la~
